Abstract

The invention discloses porous ceramics. The porous ceramics comprise, by weight, 6-10 parts of yttria, 1-3 parts of alkyl glucoside, 0.5-2 parts of sodium methallyl sulfonate, 2-6 parts of niobium pentoxide, 4-9 parts of antimony trioxide, 16-22 parts of zirconium dioxide, 5-7 parts of zinc oxide, 3-6 parts of polyester fibers, 3.6-7.4 parts of binders, 1-3 parts of triton, 4-9 parts of silicone resin polyether emulsion, 6-9 parts of sodium-potassium feldspar, 8-10 parts of aluminum hydroxide micro-powder, 1.5-3 parts of clay, 10-24 parts of porous ceramsite and 20-36 parts of emery. The porous ceramics have the advantages that gaps are uniformly reserved in the porous ceramics, the porous ceramics are in appropriate shapes, have appropriate sizes and can be used for diversified filter components, and good effects can be realized by the porous ceramics; the porous ceramics are high in mechanical strength.

Description

technical field [0001] The present invention relates to a porous ceramic. Background technique [0002] The porous ceramic material is a kind of porous ceramic material with open pore size and high open porosity, which is made of corundum sand, silicon carbide, cordierite and other high-quality raw materials as the main material, and is prepared by molding and special high-temperature sintering process. High temperature, high pressure, acid, alkali and organic medium corrosion resistance, good biological inertness, controllable pore structure and high opening porosity, long service life, good product regeneration performance, etc., can be applied to precision filtration of various media and separation, high-pressure gas exhaust silencer, gas distribution and electrolytic diaphragm, etc. However, the existing porous ceramic materials have defects such as poor brittleness, uneven distribution of pore size and shape of the material, and further improvement is needed.
