Bubble method is currently the mainstream of the international spar production methods, but also countries in the world is committed to tackling the production process in 2017 Russia's 350 kg of synthetic sapphire was identified as the world's largest, a record that a year later was our country to break.
Crystal ring electronic vice president, chief engineer Ouyang Peng root Science and Technology Daily reporter introduced bubble-artificial sapphire production bottleneck lies in automation equipment research and development and thermal design, each increase in a certain volume and quality of the core technology content and R & D process In other words, 450 kilograms and 350 kilograms of artificial stone core technology is essentially different, in this sense, our country in this area of technology research and development and production technology has exceeded Russia and other world The main production of artificial spar.
It is understood that the sapphire crystal is an ideal substrate material for semiconductor GaN / Al2O3 light-emitting diode (LED), large-scale integrated circuits SOI and SOS and superconducting nanostructured thin films, and belongs to the energy materials and optoelectronic materials that are supported and encouraged by the state.
The successful development of 450kg class will soon change the status quo of mass production of 200kg and 250kg in the area of man-made spar in our country, which will make our large-size sapphire material completely get rid of import dependence and greatly improve our country's core competition in sapphire industry Force. 'Jing Jun, general manager of ring electronics so commented.
