A MANUFACTURING METHOD OF CERAMIC PARTICLE FOR MOLD AND CERAMIC PARTICLE

摘要

PURPOSE: A method for manufacturing ceramic particle for casting and ceramic particle are provided to improve the Miscibility of molten metal and the ceramic particle by coating the surface of the ceramic particle with metal under regulated surface charge density and thermal processing condition. CONSTITUTION: A method for manufacturing ceramic particle includes the following: Ceramic particles are added in an aqueous solution with pre-set pH. The ceramic particles are dispersed in the aqueous solution to obtain a ceramic suspension solution. Metal salt is added in the ceramic suspension solution. The ceramic suspension solution is mixed to obtain a ceramic-metal mixture. The ceramic-metal mixture is filtered. The ceramic-metal mixture is dried. The dried powder is thermally processed.
