Abstract

The invention relates to a foam ceramic material. The foam ceramic material is prepared from the following raw materials by weight fraction: silicon carbide powder: 90, de-ionized water: 20, zirconium diboride: 12, polycarbosilane: 10, carborundum: 8, calcium carbonate: 8, molybdenum disulfide: 6, graphite: 5, dolomite: 5, sodium tripolyphosphate: 3, polyethylene glycol: 2, polyvinyl alcohol: 1, ammonium chloride; 1 and valeric acid: 1. The invention further discloses a preparation method of the foam ceramic material. In the invention, the ceramic material prepared by using the preparation method has the advantages of strong compression strength and bending strength, uniform foams and smaller density, and the preparation process is simple and effective.

Description

technical field [0001] The invention relates to a foam ceramic material, in particular to a preparation method and application of a silicon carbide foam ceramic material. Background technique [0002] The development of foamed ceramic materials began in the 1970s and is a porous material with high temperature properties. Its pore size varies from nanometer to micrometer, and its porosity is between 20% and 95%. Since the United States invented the use of ceramic slurry such as alumina and kaolin to successfully develop foam ceramics in 1978, and used them for aluminum alloy casting and filtration, countries such as Britain, Japan, Germany, and Switzerland have competed to carry out research, with increasingly advanced production technology and technical equipment. More and more mechanization and automation are developing, and a variety of materials have been developed, which are suitable for different purposes of foam ceramic filters such as Al2O3, ZrO2, SiC, silicon nitrid...
