ZrO2悬浮液性能研究 李明伟1,朱景川1,尹钟大1 (1.哈尔滨工业大学材料科学与工程学院,哈尔滨,150001) 摘要:采用乙醇为溶剂,PVB为分散剂和粘结剂,对固相的质量分数为55%的ZrO2悬浮液的制备和性能进行了研究.通过测定悬浮液的粘度和最终沉降体积,确定最佳分散剂含量.悬浮液的制备分两个阶段:第一阶段,悬浮液由ZrO2粉,乙醇和质量分数为0.7%的PVB(分散剂)组成,球磨24h,目的是打开颗粒团聚体和润湿粉料;第二阶段,主要是使悬浮液与粘结剂的混合,分别加入不同量的PVB(粘结剂),球磨24h.结果表明,分散剂含量为粉体质量的0.7%时,能使ZrO2粉末得到良好的分散;当粘结剂含量少于6%时,在涂层坯体过程中容易出现裂纹;而粘结剂含量高于6%时,悬浮液中含有较多的气泡.加入0.7%分散剂和6%粘结剂,可以获得粘度适中,悬浮稳定的ZrO2悬浮液. 关键词:ZrO2悬......
