After the structure separation completed, the grain size and shape factor increased with the increase of the heating time.

组织分离完成之后，晶粒的尺寸和形状系数随时间逐渐增大。

The results showed that the main crystal phase texture and distribution, the grain shape and size, pore and glass phase is the main factor that affect the mechanical strength of the material.

结果表明，晶相组成与分布、晶粒形状与尺寸、气孔及玻璃相是影响铝质电瓷材料强度的主要因素。
