METHOD FOR PREPARING POROUS SILICON CARBIDE CERAMIC CARRIER
To provide a method for preparing a porous silicon carbide ceramic carrier.SOLUTION: A porous silicon carbide ceramic carrier is obtained by: using, as main raw materials, a mixed silicon carbide powder, a silica powder, a foaming agent, a dispersant, and a thermosetting polymer emulsion; mixing them uniformly to obtain a silicon carbide slurry having a high solid content; casting the silicon carbide slurry; and subjecting the cast slurry to normal pressure sintering formation, wherein the mixed silicon carbide powder is obtained by mixing a coarse silicon carbide powder and a fine silicon carbide powder.EFFECT: The porous silicon carbide ceramic carrier can be produced which: has such advantages as high intensity, high-temperature resistance, corrosion resistance to acid and alkali; allows a ceramic substrate to be designed which varies in specifications, formation and structure according to processing requirement; and can be used individually as a filter material for separating a large-particle material. A method for producing the porous silicon carbide ceramic carrier is simple, is flexible in control of processes, is reduced in cost, is short in formation process cycle, and has values of important application and promotion.SELECTED DRAWING: Figure 1
