The invention relates to a zirconium oxide crucible and a preparation method thereof, and the preparation method comprises the following steps: S1: ball milling: carrying out ball milling mixing on zirconium oxide powder and water to obtain zirconium oxide slurry; s2, preparing a gel injection molding system: mixing locust bean gum and sodium alginate to prepare a gel injection molding system solution; s3, casting slurry is prepared, zirconium oxide powder and zirconium oxide slurry are mixed to be uniform, and then an adhesive and the gel casting system solution are added and mixed to be uniform; s4, preparing a primary crucible blank, and preparing the primary zirconium oxide crucible blank by using the pouring slurry; and S5, curing and sintering: curing and sintering the zirconium oxide crucible initial blank to obtain a zirconium oxide crucible finished product. The zirconium oxide powder is adopted as a main body, and a novel, safe and non-toxic gel casting method is combined, so that the prepared zirconium oxide crucible has excellent thermal shock resistance, the upper limit of the use temperature is increased, the zirconium oxide crucible has higher fracture toughness and bending strength, and platinum group noble metals such as platinum, palladium, ruthenium and cesium and alloys thereof can be successfully smelted.
本发明涉及一种氧化锆坩埚及其制备方法，制备方法包括以下步骤：S1：球磨，将氧化锆粉末和水进行球磨混合，得到氧化锆料浆；S2：制备凝胶注模体系，将槐豆胶和海藻酸钠混合，配成凝胶注模体系溶液；S3：制备浇筑浆，将氧化锆粉末和氧化锆料浆混合均匀，再加入胶黏剂和所述凝胶注模体系溶液混合均匀；S4：制备坩埚初坯，利用浇筑浆制备氧化锆坩埚初坯；S5：养护和烧结，将氧化锆坩埚初坯养护和烧结后得到氧化锆坩埚成品。本发明采用氧化锆粉体为主体，并结合新型、安全无毒的凝胶注模方法，制备的氧化锆坩埚具备优异的热震稳定性，且使用温度的上限有所增加，具备更高的断裂韧性和抗弯强度，可以成功熔炼铂、钯、钌、铯等铂族贵金属及其合金。
