Description
技术领域
本发明涉及一种耐火材料,特别涉及一种高抗震性氧化锆耐火材料及其制备方法。
背景技术
氧化锆是一种耐高温、耐腐蚀、耐磨损而且化学性质不活泼的无机非金属材料,尤其是其优良的耐高温、耐腐蚀性能倍受科研工作者的青睐,在20世纪20年代初即被应用于耐火材料领域。
但是,由于二氧化锆单斜型与四方型之间的可逆转变伴有体积效应,造成耐火材料烧成时容易开裂,因此单用纯氧化锆就很难制造出烧结而又不开裂的制品。现有的氧化锆高温耐火材料一般是通过向氧化锆中加入一定稳定元素氧化物的方式来实现稳定的目的。最常见的稳定元素包括锰(Mn)、钙(Ca)、稀土元素铈(Ce)、钇(Y)、铒(Er)、镱(Yb)、镝(Dy)、钛(Ti)和铪(Hf)等。它们对应的氧化物为MnO、CaO、CeO2、Y2O3、Er2O3、 Yb2O3、Dy2O3、TiO2、HfO2。
在实际使用过程中,发现采用氧化物稳定这种方式得到的氧化锆耐火材料性能多数也不理想。热震性能较差,使用过程中存在较多的开裂现象。材料开裂后多作为废品处理或者作为原料经复杂工艺提纯氧化锆。

所述的一种高抗热震性氧化锆耐火材料,其特征是:氧化锆中报废氧化锆、新制氧化锆重量占比为:报废氧化锆60%~80%,新制氧化锆20%~40%。
所述的一种高抗热震性氧化锆耐火材料,其特征是:氧化锆中报废氧化锆、新制氧化锆重量占比为:报废氧化锆70%,新制氧化锆30%,氧化锆与氧化物稳定剂所占重量比为:氧化锆95%、氧化物稳定剂5%。
