The invention discloses a high-temperature-corrosion-resistant sagger and a preparation method thereof and belongs to the field of materials. The sagger is prepared from 5-10 parts of mullite, 30-50 parts of silicon carbide, 20-30 parts of silicon dioxide, 1-5 parts of nano titanium, 5-10 parts of ceramic particles, 1-5 parts of zirconium oxide, 3-5 parts of silicon boride and 1-5 parts of aluminum oxide. The preparation method comprises the following steps: melting the silicon dioxide; adding the mullite, the silicon carbide, the nano titanium, the ceramic particles, the zirconium oxide, thesilicon boride and the aluminum oxide in parts by weight under the protection of nitrogen, and fully mixing to obtain high-temperature slurry; and molding, sintering and cooling the high-temperature slurry to obtain the high-temperature-corrosion-resistant sagger. The sagger has good anti-corrosion and high-temperature-resistant effects, the thermal stability of the material can be effectively improved, the reheating linear shrinkage rate of a refractory material is greatly reduced, the fire resistance of the sagger is improved, the service life of the sagger is prolonged, and the service lifeof the sagger is 2.8-3 times longer than that of an existing common sagger.
本发明公开了一种耐高温腐蚀匣钵及其制备方法，属于材料领域。包括莫来石5‑10份，碳化硅30‑50份、二氧化硅20‑30份、纳米钛1‑5份、陶瓷微粒5‑10份，氧化锆1‑5、硼化硅3‑5份、氧化铝1‑5份。制备方法为将将二氧化硅熔融后；在氮气的保护下加入重量份的莫来石、碳化硅、纳米钛、陶瓷微粒，氧化锆、硼化硅和氧化铝充分混合后，得到高温浆料；将高温浆料成型，烧结，冷却得到。本发明具有良好的防腐和耐高温效果，可以有效改善材料的热稳定性，大大降低了耐火材料的重烧线收缩率，提高匣钵的耐火性能，增大寿命；比现有一般的匣钵的使用寿命高出了2.8‑3倍。
