Abstract： |
The present invention relates to a method for producing ceramic component by utilizing silica sol coagulation forming process. Said method includes the following steps: mixing ethyl orthosilicate and sodium hydroxide solution, mechanically-stirring to make the ethyl orthosilicate be hydrolyzed to obtain silica sol, then adding the engineering ceramic powder into said silica sol solution, stirring and mixing then to obtain ceramic pulp material, injuecting said ceramic pulp material into a hole-free mould, coagulating at 25-10 deg.C and forming so as to obtain the ceramic blank body with required shape. |
