Preparation method of high-density corrosion-resistant fused quartz ceramic
The invention discloses a preparation method of high-density corrosion-resistant fused quartz ceramic, which comprises the following steps: mixing quartz particles, a modifier and deionized water, carrying out ball milling to obtain fused quartz fine slurry, and adding a homogenizer for homogenizing to obtain modified fused quartz slurry; adding a dispersing agent, quartz particles with different meshes and alpha-Si3N4 ceramic powder into the modified fused quartz slurry, then adding a monomer, a cross-linking agent and a pH regulator, and carrying out mixing and ball milling to obtain fused quartz mixed slurry; carrying out vacuum defoaming on the fused quartz mixed slurry, adding an initiator, injecting into a mold, heating in a water bath, curing, molding, demolding and drying to obtain a fused quartz ceramic green body; and finally, discharging glue and sintering in the air to obtain the high-density corrosion-resistant fused quartz ceramic material. The prepared quartz ceramic is reasonable in grain composition, high in sintering density, good in corrosion resistance, almost free of adhesion phenomenon, long in service life, simple in preparation process, low in cost and suitable for industrial production.
