摘要：运用透射电镜、电子衍射、元素能谱分析 ,及热膨胀系数和力学性能综合测试手段 ,研究了含 Li2 O- Al2 O3 - Si O2 ( LAS)微晶玻璃的钛酸铝陶瓷显微结构及力学性能。实验结果表明 ,LAS微晶玻璃的玻璃相促进了钛酸铝陶瓷的液相烧结而提高其力学性能 。
By means of comprehensive measures including TEM, ESR, thermal expansion coefficient and mechanical strength, the effects of LAS glass-ceramics on microstructure and mechanical properties of aluminium titanate ceramics were investigated. The results show that bending strength and Young's modulus of the ceramics increase with the reduction of apparent porosity by liquid sintering of glass phase. Microcrystallization from the glass-ceramics with low thermal expansion is responsible for low thermal expansion coefficient of the ceramics.
