The present invention discloses a production process of a ceramic cover plate, comprising the following steps of weighing: weighing solid materials respectively according to a ratio; ball milling: mixing well the solid materials, and ball-milling; mixing: mixing the ball-milled mixed power and an organic solvent according to a weight ratio of 1:(1-3) to obtain a slurry; forming: injecting the slurry respectively into a ceramic cover plate mold and a ceramic base mold, and forming to obtain a ceramic cover plate blank and a ceramic base blank; assembling: after covering the ceramic base blank with a layer of anti-adhesion powder, and assembling the ceramic cover plate blank and the ceramic base blank; sintering: placing the assembled ceramic cover plate blank and ceramic base blank in a sintering furnace, sintering at 1300-1600 DEG C for 5-20 hours to obtain the ceramic cover plate and a ceramic base; and deburring the ceramic cover plate to obtain a product. By using the production process, the product rarely deforms during sintering, product yield is increased, production cost is reduced, and product dimensional accuracy is improved.
