| 摘 要： | 以α-Al2O3微粉、板状刚玉和TiO2为主要原料,添加不同含量的ZrO2,通过高温烧成以固相反应直接合成Al2TiO5-板状刚玉-ZrO2复合材料,研究了ZrO2含量对复合材料的烧结收缩率、显气孔率、强度等的影响。结果表明:添加ZrO2的复相材料的收缩率和体积密度明显增加。ZrO2含量为4%时,可以制备出高致密度高强度的Al2TiO5-板状刚玉-ZrO2复合材料,其显气孔率为9.31%,抗折强度为25.6MPa,抗压强度为225MPa。

| Abstract: | The ZrO2-tabular alumina-Al2TiO5 composite material samples was obtained by solid state reaction and high temperature sintering with α-Al2O3 powder,tabular alumina and TiO2 as the main raw materials and adding different amounts of ZrO2.The effect of the ZrO2 content to sintering shrinkage,apparent porosity,strength of the composite materials was analyzed.The results show that: with the increase of ZrO2 additions,the density and shrinkage increased markedly.A high density and high strength of ZrO2-tabular alumina-Al2TiO5 composite material can be prepared with the content 4% of ZrO2,its apparent porosity was 9.31%,modulus of rupture of 25.6MPa,compression strength of 225MPa. |
