Silicon nitride-based ceramic chip with compact surface and preparation method thereof
The invention discloses a silicon nitride-based ceramic chip with a compact surface and a preparation method thereof, and relates to the technical field of ceramic preparation. According to the ceramic chip prepared by the invention, the volatilization of a glass phase on the surface of the ceramic chip is uniformly controlled through the coating with an inhibition effect, the formation of holes is avoided, and the density and the pressure resistance value of the ceramic chip are improved. The coating slurry is obtained by mixing and grinding burning isolation mixed powder, inhibition mixed powder, a solvent and an organic carrier, and the inhibition mixed powder is prepared by adding absolute ethyl alcohol and Span 85 into at least one of magnesium fluoride, magnesium nitride, yttrium fluoride, yttrium nitride and silicon monoxide, mixing, calcining and grinding.
本发明公开了一种表面致密的氮化硅基瓷片及其制备方法，涉及陶瓷制备技术领域；本发明所制瓷片通过具有抑制作用的涂层，从而均匀的控制瓷片表面玻璃相的挥发，避免孔洞的形成，提高瓷片的密度及耐压值。涂层浆料由隔烧混粉、抑制混粉、溶剂和有机载体混合研磨得到，其中抑制混粉由氟化镁、氮化镁、氟化钇、氮化钇、氧化亚硅中至少一种，加入无水乙醇和司盘85混合，煅烧研磨制得。
