摘要：

蓝宝石晶体具有高硬度、高机械强度, 且在紫外-可见波段优异的透过率, 是优秀的红外窗口和透明装甲材料。导模法生长的蓝宝石板材尺寸和形状接近“近净型”, 将加工的成本降到极低。南京同溧晶体材料研究院有限公司近期采用导模法成功生长出尺寸为415 mm×810 mm×12 mm的蓝宝石单晶板材。

关键词: 导模法, 蓝宝石板材, 透明装甲

Abstract:

Sapphire possesses excellent hardness, strength, and UV-IR transmittance properties, which make it as an excellent candidate for IR window and transparent armor material. Sapphire plate with large size grown by the Edge-defined Film-fed Growth (EFG) method appears “near-net” size, which can minimize processing cost. Recently Nanjing Tongli Crystal Material Institute Co., Ltd. has accomplished large size sapphire plate successfully by EFG method, with size up to 415 mm × 810 mm × 12 mm.

Key words: edge-defined film-fed growth method, sapphire plate, transparent armor
