Influence of fabrication conditions on transparency of YAG polycrystalline by solid-state reaction method

在制备YAG(钇铝石榴石)多晶体的不同条件下,对其固相反应过程中的物相变化、YAG烧结体透明程度、密度和显微组织进行了观测和分析.结果表明: Y3+的扩散速率是决定固相反应进程的主要因素,将高活性的Y2O3 纳米微粒与Al2O3 粉均匀混合,可促进固相反应的完成,使获得YAG透明体的烧结温度降低100～200 ℃,保温时间也显著缩短; 气孔和晶界对光的反射和散射是YAG多晶体透光性降低的主要原因,采用真空烧结可提高YAG烧结体的密度,改善晶体结构的均匀度,有利于提高YAG多晶体的透光性.
