Method for preparing starch-containing ceramic slurry from diatomite
The invention relates to a method for preparing starch-containing ceramic slurry from diatomite. The method comprises the following steps: (1) carrying out ball milling on a powder composition consisting of ceramic powder, starch, diatomite and optional bentonite for 4-6 hours by virtue of a ball mill, so as to obtain ball milled powder with the particle size of 5-15 microns; (2) mixing a dispersing agent with water, so as to prepare a dispersing agent solution; and (3) adding the ball milled powder into the dispersing agent solution, so as to prepare the ceramic slurry with the solid content of 60wt%-70wt%. The invention further relates to the ceramic slurry prepared by virtue of the method and application of the ceramic slurry in the preparation of porous ceramic materials. The ceramic slurry has the characteristics of high starch content and solid content, low viscosity and the like and can be used for preparing the high-porosity and high-quality porous ceramic materials.
