Improved silica ceramic core and preparation method thereof
The invention discloses an improved silica ceramic core and a preparation method thereof and aims to solve the problems of high firing shrinkage coefficient and poor high-temperature performance of a conventional ceramic core. The improved silica ceramic core is prepared from ceramic slurry and a plasticizer, wherein the ceramic slurry is formed by mixing quartz glass powder, zircon power and corundum in parts by mass; the plasticizer is formed by mixing paraffin, beewax and polyethylene. The method comprises preparation of the plasticizer, preparation of the ceramic slurry, preparation of a prefabrication material and preparation of the improved silica ceramic core. The high-temperature strength of the non-strengthened improved silica ceramic core is up to 18.614 MPa, is far higher than the strength of the existing silica ceramic core and is improved by 65.7%; meanwhile, the improved silica ceramic core has low high-temperature deflection, the high-temperature deflection at the temperature of 1,350 DEG C is 0 mm, and the high-temperature deflection at the temperature of 1,550 DEG C is 2.57 mm. The preparation method applies to preparation of the improved silica ceramic core.
