A method of manufacturing an alumina crucible
This invention belongs to the field of crucible preparation technology, specifically relating to a method for preparing an alumina crucible, comprising the following steps: Step 1: preparing a mixed solution and placing it in a ball mill; Step 2: obtaining a composite alumina slurry in the ball mill; Step 3: preparing composite alumina powder from the composite alumina slurry; Step 4: adding a binder to the composite alumina powder to obtain an alumina mixture; Step 5: molding the alumina mixture using a mold to obtain a crucible blank, wherein the mold forming process is a double-sided suction process. Compared with the prior art, the advantages and positive effects of this invention are: the double-sided suction process adsorbs fine particles in the material onto the product surface, while coarse particles are located in the middle layer of the product, thereby greatly improving the surface roughness of the finished alumina crucible, making the size of the alumina crucible more controllable, eliminating the need for a wax removal process, and effectively reducing the risk of the surface of the finished alumina crucible peeling off during use.
