Abstract

The invention discloses a ceramic gelcasting method and mould and a ceramic body so as to solve the problems that an existing ceramic gelcasting technology mould material is poor in precision and demoulding performance. The ceramic gelcasting method comprises the steps that a metal mould is placed into a drying oven to be heated; the surface of the metal mould is uniformly coated with white wax, room temperature solidification is performed, and then the ceramic gelcasting mould is obtained; the ceramic gelcasting mould is filled with ceramic slurry, and solidification forming is performed; and the ceramic slurry subjected to solidification forming is subjected to demoulding treatment, and a ceramic green body is obtained; and the ceramic green body is sintered to obtain the ceramic body. The ceramic gelcasting mould comprises the metal mould and a white wax coating. The white wax coating is used for being uniformly smeared on the surface of the metal mould, and then subjected to room temperature solidification, so that the ceramic gelcasting mould is obtained. The ceramic gelcasting ceramic body is made through the gelcasting method. The ceramic gelcasting mould implemented through the gelcasting method is good in hydrophobicity, easy to demould and easy to process.

Description

technical field [0001] The invention relates to the field of ceramic molding, in particular to a ceramic injection molding method, a mold and a ceramic body. Background technique [0002] Injection molding is an important ceramic molding method, which is widely used. Injection molding is an organic combination of traditional ceramic technology and polymer chemistry, and flexibly applies polymer monomer polymerization to ceramic molding technology. Through the preparation of low The ceramic slurry with high viscosity and high solid phase content is used to realize the molding of ceramic blanks with net size, high strength and high density. The basic principle of this process is to add organic monomers to the ceramic slurry with low viscosity and high solid phase content, and under the action of catalyst and initiator, the organic monomers in the slurry are cross-linked into a three-dimensional network structure, so that The ceramic slurry is solidified in situ, and then demo...
