1·This is mainly because of the effect of volumetric expansion which occurs when kyanite powder is transformed into mullite.
这主要是由于蓝晶石细粉向莫来石转化时发生的体积膨胀效应所致。
2·The tensile stress in matrix introduced by mullite particles made the cracks incline to extend into the matrix.
由莫来石颗粒引入的基体拉应力使裂纹倾向于向晶内扩展。
3·The substructure and the fracture process of mullite ceramics were studied by TEM and SEM.
用透射电镜和扫描电镜研究了莫来石陶瓷的亚结构特征和断裂过程。
4·After the specimens were sintered, with the decrease of the content of mullite in matrix the bend strength decreased, but the refractoriness under load increased.
达到烧结后，试样的常温强度随基质中莫来石含量的减少逐渐降低，高温荷重软化温度逐渐升高。
5·The effect of the sintering temperature and the mullite content on the dielectric properties and the bending strength has been studied.
研究了烧结温度和莫来石含量对复合材料的介电性能和抗弯强度的影响。
