Boron-nitride-based ceramic side sealing plate material for continuous strip casting and preparation method thereof
The invention discloses a boron-nitride-based ceramic side sealing plate material for continuous strip casting and a preparation method thereof and relates to a sealing plate material and a preparation method thereof. The invention aims at solving the technical problem that the service performance of the side sealing material is decreased for reasons of high the sintering temperature of the boron-nitride-based multi-phase ceramic side sealing material and low-melting-point sintering assistants. The material is made of boron nitride, electric-melting zirconia, silicon carbide and additives. The method comprises the following steps: 1) weighing raw materials; 2) preparing composite powder; 3) preparing boron nitride composite powder; 4) preparing the prefabricated blank of the boron-nitride-based ceramic side sealing plate material; 5) preparing the boron-nitride-based ceramic side sealing plate material for continuous strip casting. The compactness of the boron-nitride-based ceramic side sealing plate material for continuous strip casting prepared by adopting the method disclosed by the invention can reach more than 97 percent, the comprehensive mechanical performance is excellent and the anti-bending strength can reach 420MPa. The invention belongs to the field of preparation of ceramic side sealing plate materials.
