Preparation method for high-density hexagonal boron nitride ceramic material |
| abstract |
The present invention relates to a method for producing a high-density hexagonal boron nitride (hBN) ceramic material, wherein the surface of the tetraethyl orthosilicate powder is covered with uniformly dispersed SiO 2 and then sintered at a high density The hBN ceramic material is obtained, and the relative density of the produced hBN ceramic material reaches 80% or more. The above manufacturing method is a method in which the surface of the hBN powder is treated with SiO 2 Wrapped in the nano SiO 2 layer By uniformly dispersing the sintering aid and combining with high-temperature atmospheric pressure sintering, high-density hBN ceramics are obtained, which reduces the amount of SiO 2 used and improves the high temperature service temperature and high temperature performance of hBN. |
