The table A is the relation between the mechanical properties of heterogenicity ceramic material and the content of firing assistant. To analyze the table A, the strength of heterogenicity ceramic material to counter distorting is obviously improved with the increase of the content of firing assistant. The reasons are as follows: Firstly, the firing assistant in systems produces liquid phase to accelerate the material compactification, to increase the density of material, so the material has a high mechanical strength; In the second, the measurement of material grain crystal becomes thinning with adding B, while the structure of small crystal is benefit to endow the good mechanical properties to materials; At last, the added flexible phase B may be dissolved into the crystal lattice of stable phase C. When the content of firing assistant is D%, the strength of heterogenicity ceramic material to counter distorting is E MPa. While the the content of firing assistant has increased to F%, the strength to counter distorting has the maximum, G MPa. But it will decline with the continued increase of the content of firing assistant, and when the content of firing assistant increase to H% or K%, the strengths of samples to counter distorting will respectively decrease to L MPa and T MPa.

Table A showed the correlation between the mechanical properties of composite ceramic material and the content of sintering aid. The bending strength of composite ceramic material improves significantly as the content of sintering aid increases, according to table A. That can be attributed to three factors. First, the liquid phase produced by the sintering aid can promote the compacting and increase the density of material, thus improving the mechanical properties of material. Second, the addition of B refines the grains, which helps improve the mechanical properties of material. Third, the solution of the added soft phase B to the hard phase C lattice may contribute to the improved mechanical properties. The bending strength of composite ceramic material was only E MPa when the content of sintering aid was D%, and reached the maximum value (G MPa) as the content of sintering aid increased to F%. Further addition of sintering aid would decrease the bending strength of the composite ceramic material; as the content of sintering aid increased to H% and K%, the bending strength of sample decreased to L MPa and T MPa, respectively.

Table A showed the relationship between the mechanical properties of heterogenicity ceramic material and the content of firing auxiliaries. It demonstrated that the bending strength of composite ceramic materials improves obviously with the increase of the content of firing auxiliaries. The liquid phase produced by firing auxiliaries make the material compact and have a high density and the addition of B refined the grain size advance the mechanical property as well as the solution of the additive soft phase B to the hard phase C lattice may contribute to enhance the mechanics strength. The bending strength of composite ceramic materials was E MPa when the content of firing auxiliaries was d% and had the maximum value G MPa with the addition of firing auxiliaries increased to F%. Then it decreased with the increasing of firing auxiliaries and reduced to L MPa and T MPa with dosage of firing auxiliaries increased to H% and I%¡£
