The first one hundred kilograms of sapphire crystal in Jiangsu came out of the constraints LED industry development bottleneck is broken

In June 28th, with a red silk cloth cover slowly lifted, a transparent appearance, a sapphire crystal cylindrical officially unveiled in Jiangsu Yangzhong, it weighs 101.35 kg, is the largest domestic sapphire crystal by human technology can produce is the most important. It was born, to provide high-quality materials for the rapid growth of China's LED industry, also means that the passive situation in China's growth, sapphire crystal substrate manufacturing market long-term dependence on imports is being broken, plays an important role to improve the LED industry chain.

According to the on-site technical personnel, this super hundred kilograms of sapphire crystal, is jointly developed by the technical team of Jiangsu Jetion New Material Co. Ltd. and the United States, Switzerland and other foreign experts, it is made of "unique growth technology of in situ growth and in situ annealing", as the sapphire single crystal of high quality, the process to solve the the crystal growth quality is not stable, not the specifications and other many problems. The successful trial production of the first furnace provides the possibility of large-scale production and upgrading to the larger size of the gem.

In recent years, the LED industry in the global scope of the rapid development, its products are widely used in lighting, blue laser field, especially applied to the liquid crystal display, the market is expanding rapidly, almost 100% of the more than 50% of the notebook computer, LCD TV in the application. In this huge LED industry chain, sapphire crystal growth, substrate manufacturing is in the front of the LED industry chain, is the largest investment, the highest technical barriers, the maximum value of each link, the manufacturing process are needed to support the high technology and exquisite production management, rely on technology and equipment very strong, because of this, China's high brightness of blue LED epitaxial wafer etc. the demand is almost entirely dependent on imports. The birth of the Jiangsu Jetion sapphire crystal size, can be said to solve the LED industry chain bottleneck significant breakthrough.

With this new technology Jiangsu Jetion New Material Co Ltd has been in the implementation based on sapphire crystal growth development of their future, they are building a project, investment 1 billion yuan to create LED sapphire substrate by directional, dig stick, cutting, grinding and polishing, cleaning and detection of a series of complex and fine processing. From crystal to chip cutting, grinding, polishing and final quality control to meet market demand and customer service. Expected in August this year, after the formation of an annual output of 5 million sapphire substrate size, annual sales of over $1 billion 200 million.
