Sintering aid for preparing silicon nitride ceramics, application of sintering aid and preparation method of silicon nitride ceramics
The invention relates to the technical field of silicon nitride ceramics, and in particular, relates to a sintering aid for preparing silicon nitride ceramics, an application of the sintering aid and a preparation method of the silicon nitride ceramics. The invention provides the sintering aid for preparing the silicon nitride ceramics. The sintering aid comprises a component A, a component B and a component C; the particle size of the sintering aid is less than or equal to 100 nm; the mass ratio of the component A to the component B to the component C is (1-5):(1-10):(1-10); the component A comprises titanium dioxide; the component B comprises boric oxide, magnesium oxide or calcium oxide; and the component C comprises a rare earth metal oxide. The sintering aid can effectively improve the mechanical property of the silicon nitride ceramics.
