Both unit cell parameters and fractional atomic coordinates of β-Si_3N_4 have been fully relaxed using Crysta106 program that adopts all-electron gauss-type basis sets and the density functional theory (PW91 and B3LYP).
分别用PW91,B3LYP两种密度泛函方法和全电子高斯基组对β-Si3N4的几何结构进行全优化(包括晶格参数和原子坐标),结果和实验值符合良好。
4) β-Si3N4 grains
β-Si3N4晶粒
1.
The results reveal that the diameter and aspect ratio of elongated β-Si3N4 grains in the composites decrease with increasing h-BN content.
结果表明:随着h-BN含量增加,柱状β-Si3N4晶粒的直径和长径比均下降;未加h-BN时,β-Si3N4陶瓷以沿晶断裂为主,添加体积含量为6%和8%的h-BN后,复合材料出现明显的沿晶和穿晶断裂,而添加10%h-BN的陶瓷复合材料则以沿晶断裂为主。
5) β Si 3N 4 single crystal particles
