Preparation method of porous yttrium oxide crucible, large-size crucible and application of large-size crucible in titanium-aluminum alloy smelting
The invention discloses a preparation method of a porous yttrium oxide crucible, a large-size crucible and application of the large-size crucible in titanium-aluminum alloy smelting, belongs to the field of oxide ceramic crucibles, and aims to solve the problem that the yttrium oxide Y2O3 crucible has good mechanical properties and thermal shock resistance at the same time. The preparation method comprises the following steps: adding 30-40% by mass of yttrium oxide Y2O3 electric smelting mixed powder with the particle size of 1-3mm, 20-40% by mass of yttrium oxide Y2O3 electric smelting mixed powder with the particle size of 60-300 meshes and 20-30% by mass of yttrium oxide Y2O3 electric smelting mixed powder with the particle size of 1-3mu m into grinding balls for ball milling, granulation treatment, cold isostatic pressing and the like to obtain a crucible green body, sintering the crucible green body at 1650-1750 DEG C, and cooling to room temperature to obtain the high-purity yttrium oxide ceramic crucible. The porous yttrium oxide crucible has the effect that the crucible can have good mechanical properties and thermal shock resistance at the same time.
多孔氧化钇坩埚的制备方法及大尺寸坩埚和其在钛铝合金熔炼中的用途，属于氧化物陶瓷坩埚领域，为了解决氧化钇Y2O3坩埚同时具有良好的力学性能和抗热震性能的问题，将质量计30％～40％的粒径1～3mm氧化钇Y2O3电熔混合粉、20％～40％的粒径60～300目氧化钇Y2O3电熔混合粉以及20％～30％的粒径1～3μm氧化钇Y2O3电熔混合粉加入研磨球进行球磨、造粒处理、冷等静压成型等得到坩埚生坯，坩埚生坯在1650℃～1750℃进行烧结，冷却至室温，得到所述多孔氧化钇坩埚，效果是坩埚能够同时具有良好的力学性能和抗热震性能。
