摘要

以α-Al2O3、金红石型TiO2和MgO为初始粉料

采用凝胶注模成形工艺制备了Al2（1-x）MgxTi1+xO5固溶体陶瓷。将陶瓷试样浸泡到750℃的铝熔体中20min

取出后用自来水冷却

测试热震后试样的残余抗弯强度

并研究了x值变化对固溶体陶瓷抗热震性的影响。结果表明

随x值的增大

陶瓷的抗热震性先快速提高后趋于缓慢。当x=15%时

试样经5次热震后强度保持率为87%

具有优良的抗热震性能。

Abstract

The Al2（1-x）MgxTi1+xO5 solid solution ceramics were prepared by gelcasting withα-Al2O3

rutile-TiO2 and MgO as the raw powder.Samples prepared were soaked in the aluminum melt at 750℃ for 20min

and then cooled with water.The residual strength of the samples after five thermal shock was tested.Influence of xvalues on the thermal shock resistance of the solid solution was investigated.The results indicate that with the increase of xvalues

the thermal shock resistance is increased quickly firstly and then slowly.When xvalue is 0.15

the strength retention rate of the samples prepared keeps 87% after 5 thermal shock

showing excellent thermal shock resistance.
