GSPL-SNCS silicon nitride tape casting slurry
The invention provides a GSPL-SNCS silicon nitride tape casting slurry which at least comprises an inorganic matter solid of Si3N4 powder and mixed powder of Y2O3, TiC, MgSiN2 and Mg3N2, and the proportion of TiC in the mixed powder is 0.1-10%; tiC is added into the GSPL-SNCS silicon nitride tape casting slurry, the TiC stably exists in a silicon nitride matrix at the optimal temperature of 1725 DEG C, and the TiC can enhance the silicon nitride ceramic at the optimal temperature of silicon nitride, so that the silicon nitride ceramic can be enhanced, and the service life of the silicon nitride ceramic can be prolonged, the service life of the silicon nitride ceramic can be prolonged, and the service life of the silicon nitride ceramic can be prolonged. The yield of a GSPL-SNCS silicon nitride tape casting slurry product is greatly improved, the thermal stability of the product is improved, and the mechanical strength of the product is improved.
本发明提供一种GSPL‑SNCS氮化硅流延浆料，至少包含Si3N4粉体、Y2O3+TiC+MgSiN2+Mg3N2混合粉体的无机物固体，在所述混合粉体中TiC占比为0.1‑10%；以及至少包含蓖麻油、无水乙醇、聚甲基丙烯、聚乙烯乙二醇和单油酸甘油混合物的有机物胶体，在GSPL‑SNCS氮化硅流延浆料中加入TiC，在最优温度1725℃时，TiC稳定存在于氮化硅基体中，TiC能够在氮化硅获得最优温度下增强氮化硅陶瓷，极大的提升GSPL‑SNCS氮化硅流延浆料制品的良率，提升制品热稳定性，提升制品机械强度。
