【摘要】 本文介绍了根据铱坩埚直径,选用合适粒度和厚度的氧化锆保温砂制做高效率的感应线圈,从而降低了感应加热提拉法生长高熔点氧化物晶体的加热功率。同时介绍了如何解决氧化锆保温罩和石英坩埚在晶体生长中破裂的问题。更多还原

【Abstract】 By chosing suitable grain size and thickness of zirconia insula-ting powder around Ir crucibles and using a more effective induction coil,theheating power required in crystal growth by CZ technique is greatly lowered.In addition,measures to prevent the craking of quartz crucible are pro-posed.更多还原
