摘　　要：自主研制出了可用于超高温晶体生长炉温场的高纯钇锆固溶体陶瓷制品,在真空、保护气氛、空气环境使用温度达到2650℃,反复升降温周期使用寿命达到3年,较金属温场提升6倍寿命。以使用该陶瓷制备的温场生长120 kg级晶体为例,其晶体生长周期较金属钨钼温场缩短约25%,节省能耗40%以上,同时还可避免金属材料高温时出现的过收缩、破裂等问题,提高了安全性和生产效率,并且实现了材料的绿色环保和循环利用。The yttrium zirconium solid solution ceramics were independently developed,which can be used in temperature field of ultra high temperature crystal growth furnace.The highest use temperature is 2650℃in vacuum,protective atmosphere and air environment.The service life of this material reaches 3 years with repeated rising and cooling cycle,which is 6 times longer than the metal temperature field.Taking the ceramic temperature field of 120 kg crystal as an example,it shortens the growth cycle by 25%and saves more than 40%of the electric energy consumption compared with the metal temperature field.At the same time,it avoids metal materials at high temperature the problems such as shrinkage,rupture,improves the safety and production efficiency,and implements the green environmental protection and recycling of materials.
