用DSC、XRD、SEM、FTIR和显微硬度计研究了Ge23Se67Sb10红外玻璃组织、硬度和红外透过率随热处理温度和时间的变化规律.结果发现,Ge23Se67Sb10红外玻璃的微晶化主要受热处理温度的影响,只有当热处理温度超过310℃后,才可用XRD和SEM检测出析晶峰和析晶相.微晶Ge23Se67Sb10玻璃的力学和光学性能与热处理温度和时间有关,温度低于310℃时,微晶Ge23Se67Sb10玻璃的硬度随热处理温度的升高和热处理时间的延长而缓慢增大,而其红外透过率随热处理温度和时间的变化很小;温度达到310℃后,其硬度和红外透过率随热处理温度的升高和热处理时间的延长而急剧减小.在310℃热处理70 h后,微晶Ge23Se67Sb10玻璃的显微硬度比原样提高了20％、透过率在2～12 μm波长区域内仍高达50％.
