摘　　要：通过对试样的断裂强度、断裂韧性、相对密度、气孔率、玻璃相含量以及显微结构的研究 ,探讨了 Cr2 O3、Mn2 O3的添加对 ZTM陶瓷常温性能的影响。实验结果表明 :Cr2 O3、Mn2 O3的添加对 ZTM陶瓷材料产生了完全不同的影响。Cr2 O3的颜色在不同方法制备的试样中 ,呈现不同的颜色变化。Mn2 O3的添加可以增加试样的玻璃相含量 。The effect of the Cr 2O 3 and Mn 2O 3on properties of ZTM composites has been discussed by means of the studies of the bending strength,toughness,porosity,relative density,the residual glass content and microstructure.The results showed that the influence of Cr 2O 3 content on properties of ZTM composites was not obvious.The manufacture methods were the important reason for color changes of Cr 2O 3 doped specimens.With the Mn 2O 3 content increasing,the residual glass content of specimens would increase,but the bending strength decrease.
