一种高抗热震性氧化锆耐火材料及其制备方法
摘要：
本发明提供一种高抗热震性氧化锆耐火材料及其制备方法，由如下重量比的组分构成：氧化锆90%~99%；氧化物稳定剂1%‑10%，所述氧化物稳定剂为CaO、MgO、Y­2O3或CeO2，所述氧化锆包括报废氧化锆和新制氧化锆，氧化锆中报废氧化锆、新制氧化锆重量占比为：报废氧化锆50%~90%，新制氧化锆10%~50%。将报废氧化锆经除杂破碎后与新制氧化锆及稳定剂通过有机粘结剂进行搅拌混合，制坯、烧结后制备而成。本发明利用报废氧化锆耐火材料作为主体，加入新的氧化锆及稳定剂作为连接材料，形成的高抗热震性氧化锆耐火材料可有效避免开裂，且性能稳定。
摘要（英）：

The invention provides a zirconium oxide refractory material with high thermal shock resistance and a preparation method of the zirconium oxide refractory material with high thermal shock resistance.The zirconium oxide refractory material is prepared from, by weight, 90%-99% of zirconium oxide and 1%-10% of an oxide stabilizer, wherein the oxide stabilizer refers to CaO, MgO, Y2O3 or CeO2; the zirconium oxide comprises, by weight, 50%-90% of scrap zirconium oxide and 10%-50% of newly prepared zirconium oxide. The zirconium oxide refractory material is prepared by steps: decontaminating and crushing the scrape zirconium oxide, stirring and mixing with the newly prepared zirconium oxide and the stabilizer through an organic binding agent, and performing blank making and sintering to obtainthe zirconium oxide refractory material. By adoption of a scrape zirconium oxide refractory material as a main material and adoption of the new zirconium oxide and the stabilizer as connection materials, the formed zirconium oxide refractory material with high thermal shock resistance is capable of effectively avoiding cracking and stable in performance.
