So, there are F(0)=G(0)=0, F(2)=G(2)=1, 0≤F(D) ≤1, 0≤G(D) ≤1. (3) The particles of raw material are fractal dimension similar to each other despite their different size [7].
Model for the optical proportion.In this study, the raw material is divided into 4 segments in size (0~0.088mm, 0.125~0.3mm, 0.5~1.0mm and 1.0~2.0mm).
The distribution patterns of raw materials were shown in Fig.1 Fig.1 Accumulated content of mass for different raw materials It can be seen from the Fig.1 that the curves of accumulated content of mass versus particle size were linear, which means the particles size at any segment in this study was uniform distributed.

The intrinsic brittleness and hardness of silicon nitride ceramics, however,
make it difficult and costly to machine them into complex-shaped components[1,2].
