The world’s largest Sapphire form

In Sri Lanka, “jewel city” Ratnapura gem minerals found in the largest Sapphire in the world, recently unveiled the world’s veil.
Its weight is amazing, 1404.49 CT, equivalent to about 280g (less than 10 ounces). Local gemologists say they have never seen a more Sapphire.
This is called “light stone” a type of gem, six-pointed stars shine above, is reflected from the inside of the Crystal.
Anonymous master to the BBC that the precious stones can sell for $ 175 million. BBC the wiring of the University of Cambridge mineralogist Simon Redfern, exploring the gems form.
Like the large sapphires are very rare
Formation of the Sapphire is a very long process. This particular Sapphire in rocks formed in the Highlands of Sri Lanka. Most rocks are granite, by solidification of molten magma cools down, formed under the scorching heat and high pressure.
Sapphire Block Sapphire Block
“Granite has been identified here for nearly 2 billion years of history. And more than 500 million years ago, massive mountains formed of metamorphic rocks, rock was squeezed restructuring. Temperature, the root causes of these mountains has more than 900 degrees Celsius, the pressure more than 9000 atmospheric pressure. ”
Sapphire might formed before the granite restructuring, or later when the rock was formed when heated and compressed.
Redfern said: “no matter what the situation, temperature and pressure in a million years is very slow. Such crystals can grow so large. ”
Small uncut sapphires, relatively common in Sri Lanka
Gem formed squatted on the rocks and mountains uplifted crust, rock was uplifted and eroded. “The rocks were brought to the surface after rain erosion and weathering, will be sent into the River, to the sand-stones of dalatenapule farm. ”
Sapphire mineral in the journey survived because they were hard enough. Relatively softer rock erodes into the mud and sand, conducive to the formation of the heavy rains in Sri Lanka the riverbed.
Sapphire is so hard is because they are made up of corundum, aluminum oxide. “Corundum is a hard guy, can be used as Abrasives on the sandpaper. ”
“If you add tiny amounts of iron and titanium to alumina in aluminum-oxygen mixture, and growing, you can create sapphires. Sapphire is the ‘ impurities ‘ corundum – with traces of iron and titanium. ”

News from the industry, Harbin aoruide backdoor Southwest pharmaceutical industry listing has attracted great attention in the market, and the event is expected to lead to excess income of the Sapphire plate. Southwest pharmaceutical industry August 12 announcement said the company intends to 7.42 Yuan after the asset exchange 497 million shares was aoruide a 100%/unit ownership and plans no less than 7.42/increase does not exceed 138.814 million shares to aoruide “expansion project of large size Sapphire materials industrial base” and the fall of electro-optical “Sapphire Windows base project”. Zuo Hongbo, one of the first and aoruide the actual controller of the company assets replacement; aoruide 100% owned by difference of replacement parts to the shareholders by the company increased acquisitions asset replacement is complete, Zuo Hongbo to reset all of their access to the assets of 413 million yuan in cash and 29.99% shares of the company held by the Tai Chi group. After the transaction is completed, the company’s main business will be turned into sapphire crystals and crystal growing furnace equipment suppliers.
Apple and Sapphire “scandal” is often effective catalysts to stimulate the Sapphire concept gains. Market that Apple will bring Sapphire industry leaps. Industrial securities said that through research and the Apple of Apple patent cooperation with GTAT 578 million dollars, Sapphire will cover but about Apple’s future strategic materials, reflected Apple’s layout in the long run. IPhone application once the Sapphire plate, Sapphire industry development. 2014 LED substrates and Sapphire window size of about 5 billion yuan, from 2015 to 2016 is expected Apple Sapphire cover demand will reach 7.5 billion yuan, 9.3 billion yuan, non-Apple Sapphire cover demand will reach 4 billion yuan, 7 billion yuan.
In addition, the LED industry demand for sapphires is still increasing steadily. Sapphire has superior electrochemical, optical and thermodynamic properties, is widely used in LED, VLSI SOI and SOS, superconducting Nano-thin film substrates as well as infrared, such as military installations, high-intensity laser window material, which LED a long Sapphire the major share of the market, data shows that 2013 LED 78% per cent of total demand for sapphires. Benefit from the outbreak of the LED lighting market, LED industry is still in a period of rapid growth, has predicted the future 5 years LED the market demand for Sapphire’s compound growth rate will remain at about 30%.
In stock configuration, xingye securities said that future Apple Sapphire largest suppliers are expected to 40% per cent global market share (about 20% is currently the world’s largest market share of the company), so that there is 10 times more than double the growth, is the industry’s most valuable company. From Apple’s demands, technology, low cost junior capacity and size of businesses are most likely to be Apple’s suppliers.
Based on the above logic, aoruide the world’s largest production capacity, long good grain quality, cost control, Lan Si reserves large cutting capacity and has invested heavily in extending upstream, is by far the most valuable companies and proposals concern Tong Feng sheng electrical electronics and ceramics.

Sapphire market confusing Windows and du Mai still pass

On April 18, 2015, Southwest pharmaceutical (600666.SH) publish a bid aoruide report on the acquisition, announced Southwest pharmaceutical aoruide successful backdoor access to capital markets.

Aoruide is mainly engaged in Sapphire Crystal, crystal growing furnace and Sapphire products development, production and sales, production of 2 inches, 4 inches, 6 inches and above size Sapphire ingot and products, products in addition to the main LED substrate material, the 2011 entered consumer electronics applications, supply of Sapphire materials to optical Lan Si technology and Byrne.

Report shows that aoruide plan through the trading capital market, making full use of financing function of the capital market, seize the opportunities of the Sapphire industry exploded, quickly to the Sapphire materials processing and downstream application product development, promotion and consolidation of aoruide in the industry and the dominant position in the market.
Aoruide 2013 Sapphire ingot sales revenues of 245 million Yuan, sales or 2 inches around 1,190.310,000 mm, respectively, global demand for ingot sales revenue 17.51% and 15.34%, the world leading position.
In consumer electronics, window film, aoruide can supply square cut Sapphire products, including 2-inch and 5-inch sizes.
2-inch specification blocks on the market mainly for smart wear products, such as AppleWatch window protection film; a five-inch specification material focuses on smart phones cover product.
2014 years Apple and blue Sapphire GT storm, Sapphire film market has been in a confusing State of the window.
In the traditional consumer market, Sapphire decorations appear in a small size, produced by low-cost, high-efficiency flame method. As the application cover sheet, equipped with electronic or mechanical lenses, and action buttons on the cover sheet of a variety of products, such as fingerprint identification plate hot market right now.
Constant temperature liquid crystal growth technology, Sapphire, more are used in the semiconductor industry and large scale applications for optical observation window, and was very good at “military” is applied to “civilian” Apple extended to the field of consumer electronics.
Due to thermostat melt liquid long Crystal process can production optical level of Sapphire Crystal, can solution effect color display displayed uniform and capacitor screen of penetrating rate problem and was phone producers are concern, also makes these involved Sapphire business of enterprise on consumption electronic market application is vision, although industry still didn’t solution Sapphire application in phone Shang of process and material cost, but with AppleWatch of promoted, Sapphire application in can wear field of market is slow opened, to many of enterprise brings has imagine of space.
Aoruide backdoor Southwest pharmaceutical industry to enter the main purpose of the capital markets, is to take power of the capital markets, can survive the Sapphire consumer electronics, optical-grade window film square blocks in the production process of high manufacturing costs, take advantages of Lan Si suppliers of optical technologies and Byrne, quickly occupied the market.
But the Windows are square blocks the technical requirements and technical requirements of traditional semiconductor substrate is not exactly the same, Windows are square cut out now with seven or eight years ago, Panel companies treat similar to a touch screen: perceived technical requirements is not high, actual production yields are very low.
Sapphire window, the main obstacle is still processing difficulty causes high cost, how to reduce terminal costs is eager to solve the problems of the industry. But in the current market, really open up from low-cost materials, low-cost long-grain to lower-cost manufacturing, and low-cost technical parameters such as application context of enterprise yet.
Optical Bowen had also set up his own smile boenlu manufacturers, will not authorized by Apple technical support, or in the future is unknown, but it would certainly reduce the aoruide, now known as Southwest pharmaceutical industry’s reliance on Southwest pharmaceutical industry want to quickly obtain profits on Sapphire business, it seems also have to strengthen the Sapphire window films outside the market.
