进一步的，上述稳定锆捣打料的制备方法中，所述钇稳定锆中氧化钇的质量百分数为7％-9％。
进一步的，上述稳定锆捣打料的制备方法中，所述步骤5中的烧结具体为：加热升温180min升温至1200℃，保温4-6h；180min内降温至室温。
进一步的，上述稳定锆捣打料的制备方法中，所述步骤2中的石英石的粒度为200目，二氧化硅的质量百分含量为：55-60％。
本发明的另一技术方案为提供一种上述稳定锆捣打料的制备方法制备的稳定锆捣打料。
本发明的有益效果在于：本发明稳定锆捣打料及其制备方法中，使用稳定锆制作捣打料，能够明显提升普通氧化锆捣打料的硬度强度以及耐腐性能，使最终烧结成型的稳定氧化锆成为优良的耐火材料。同时整个操作过程不产生废弃废料，安全环保。具体的，本发明稳定锆捣打料是使用复合稳定锆、石英、硼酸按一定比例混合，以磷酸铝为结合剂烧结而成。它的优势在于高温下导热率较低，抗热震性较强，化学性稳定，对熔融的二氧化硅及液态金属都具有良好的耐蚀性。能在氧化气氛下稳定工作，不与熔融金属发生化学反应，是一种优良的耐火材料。广泛应用在三项电弧炉炉盖，循环硫化床锅炉等领域。
