The invention discloses a calcium oxide crucible and a preparation method thereof, and belongs to the technical field of refractory materials, the calcium oxide crucible comprises, by mass, 78-97% of composite calcium oxide, 2-15% of YSZ fiber and 1-5% of a composite sintering aid, the composite calcium oxide comprises calcium oxide sand and calcium oxide fine powder with different particle sizes, and the YSZ fiber comprises calcium oxide sand and calcium oxide fine powder with different particle sizes. The proportion of the calcium oxide sand in the composite calcium oxide is greater than that of the calcium oxide fine powder. The calcium oxide sand and the YSZ fibers in the composite calcium oxide are used for carrying out particle and fiber hybrid reinforcement on a calcium oxide matrix, and the technical effect of improving the thermal shock resistance of the crucible is achieved.
本发明公开了一种氧化钙坩埚及其制备方法，属于耐火材料技术领域，以质量百分比计，所述氧化钙坩埚包括：78％‑97％的复合氧化钙、2％‑15％的YSZ纤维和1％‑5％的复合烧结助剂，所述复合氧化钙包括不同粒径的氧化钙砂和氧化钙细粉，所述复合氧化钙中所述氧化钙砂所占的比重大于所述氧化钙细粉所占的比重。本发明通过复合氧化钙中的氧化钙砂和YSZ纤维对氧化钙基体进行颗粒和纤维混杂增强，实现了提高坩埚的抗热震性的技术效果。
