3 Terms and Definitions
GB/T 9530-1988 and defined the following terms and definitions apply to this document.
3.1 Microstructure
Composition of the crystalline phase (main phase, the second phase which), glass phase, gas, grain boundaries, shape, size, number, type, distribution, uniformity, defects, phase
Mutual relations between permutations and combinations of substances in space.
3.2 Crystal phase
Crystals formed in part by a multiphase system.
3.3 Stomatal pore
Present in the pores of the ceramic body. Said communicating with the atmosphere of open pores and closed, said closed pores, said Jing package within the interior of the gas in the grain
Holes in said intergranular pores between the grains.
3.4 Glass phase
Constituted by the glassy part in multiphase systems. It is coagulated by the major components, additives and impurities melted together.
Preparation of 4 samples
Where appropriate, and the sample size. For the small size of the sample, it can be directly used single-sided grinding; general sample desirable 10mm × 10mm ×
