Zirconium refractory material preparation method
The invention discloses a zirconium refractory material preparation method, and belongs to the technical field of zirconium refractory materials, the method comprises the following steps: material preparation: weighing yttrium oxide powder and cobalt oxide powder according to a ratio, the addition amount of the yttrium oxide powder being 5%; adding a forming agent; carrying out ball milling on the mixed ingredients; drying the ingredients subjected to ball milling; the dried ingredients are molded; and sintering the formed semi-finished product to obtain a product. 5% (mol) yttrium oxide-zirconium oxide can obtain the highest density, the maximum linear shrinkage rate and the moderate porosity; the tetragonal-phase and small-cubic-phase high-purity zirconium oxide product obtained by the invention can effectively solve the problem of use limitation at high temperature. The thermal stress is reduced by changing the composite phase of the material, so that the problem of material cracking is solved.
本发明公开了一种锆质耐火材料制备方法，属于锆质耐火材料技术领域，该方法包括：配料：将氧化钇粉末和氧化钴粉末按配比称重，氧化钇粉末添加量5%；加入成型剂；对混合后的配料进行球磨；对球磨后的配料进行干燥；对干燥后的配料进行成型；对成型后的半成品进行烧结获得制品。5%（mol）氧化钇‑氧化锆能获得最高的致密度、最大的线收缩率和适中的气孔率；本发明获得的四方相和少量立方相的高纯氧化锆制品，能有效解决在高温中限制使用的问题。通过改变材料的复合相降低热应力，进而解决材料开裂的问题。
