The size, shape, and orientation of the grains play a key role in many of the macroscopic properties of these materials, for example, mechanical strength. In most ceramics, more than one phase is present, with each phase having its own structure, position, and properties. Control of the type, size, distribution, and amount of these phases within the material provides a means to control properties. The microstructure of a ceramic is often a result of the way it was processed. For example, hotpressed ceramics often have very few pores. This may not be the case in sintered materials.（P99 第一段） 多晶陶瓷的結(jié)構(gòu)中包含很多晶粒。陶瓷的微觀結(jié)構(gòu)經(jīng)常是它的加工方式造成的結(jié)
