摘要

采用凝胶注模工艺分别制备体积分数为36%、38%、40%、42%和44%的ZrO2陶瓷坯体

在1 600℃进行无压烧结

通过电子万能试验机、扫描电镜等测试手段分别对ZrO2陶瓷材料的力学性能和显微结构进行测试和分析

结果表明

固相体积分数为38%时

陶瓷材料的相对密度、抗弯强度和断裂韧性最大

分别为98.36%、921.34MPa和11.49MPa.m1/2

这是由于固相体积分数为38%的浆料流动性好

气孔少

制备出的ZrO2陶瓷坯体缺陷少.

Abstract

In this paper

the green body of ZrO2 ceramic were successfully prepared by gel-casting

of which solid contents are 36%

38%

40%

42% and 44%

respectively

then no pressure sintered at 1600℃

the property and microstructure of ZrO2 ceramic were investigated by Electronic Universal Testing Machine and SEM.The results show that

when solid content is 38%

they are the greatest value that the relative density

bending strength and fracture toughness of ZrO2 ceramic

which are 98.36%

921.34MPa and 11.49MPa·m1/2

respecti...
