Preparation method of silicon oxide ceramic core
The invention discloses a preparation method of a silicon oxide ceramic core, belonging to a preparation method of a ceramic core. The invention aims to solve the problems of low firing bending strength and poor high-temperature performance of conventional silicon oxide ceramic cores. The preparation method comprises the following steps: 1, uniformly mixing paraffin and beewax to obtain a plasticizer; 2, uniformly stirring 70-80 parts by mass of quartz glass powder, 6-12 parts by mass of zirconium silicate powder and 6-10 parts by mass of cristobalite powder, and carrying out heat preservationtreatment to obtain ceramic slurry; 3, adding the ceramic slurry into the molten plasticizer, and conducting uniform stirring to obtain a ceramic mixture; and 4, adding the ceramic mixture into a mold, and carrying out pressing and sintering treatment to obtain the silicon oxide ceramic core. According to the silicon oxide ceramic core, the quartz glass powder is used as a matrix, the cristobalite powder and zirconium silicate powder are used as additives, the paraffin and the beewax are used as plasticizers, and a mold pressing method is employed to prepare the silicon oxide ceramic core; and the bending strength of the silicon oxide ceramic core is high, and the high-temperature deflection of the core is reduced.
