450 kg泡生法蓝宝石晶体成功生长
|
摘要
采用自主研制的泡生法长晶炉,成功生长出全球最大的450 kg蓝宝石晶体,可加工形成615 mm×415 mm大尺寸蓝宝石面板,气泡度达到A级以上。该晶体可产出6000 mm长、4 inch直径的LED级晶棒,单位毫米成本相比150kg晶体下降45%以上。
450 kg sapphire crystal was grown successfully by the self-developed KY furnace. It is the largest sapphire crystal reported so far in the world. Sapphire panel with dimension of 615 mm × 415 mm was obtained from the sapphire,with bubble degree rated grade A. Also,the crystal boules can produce LED-grade 4-inch diameter crystal rods up to 6000 mm,with a45% lower cost per mm compared to that of 150 kg crystal.
