-
If there is a large difference in the coefficient of expansion, there will be cracks in the ceramic layer or the phenomenon of exploding porcelain in the alternating heat and cold.
如果膨胀系数相差较大，在冷热交替的时候就会出现瓷层裂纹或爆瓷现象。
膨胀系数是表征物体热膨胀性质的物理量，即表征物体受热时其长度、面积、体积增大程度的物理量。长度的增加称“线膨胀”，面积的增加称“面膨胀”，体积的增加称“体膨胀”，总称之为热膨胀。
