Abstract

The invention relates to the technical field of ceramics and particularly relates to porous ceramics adopting a biomass powder material as a pore former. The porous ceramics are prepared from the raw materials in parts by weight: 50-75 parts of cordierite powder, 5-10 parts of black mud powder, 10-20 parts of powder coal, 10-30 parts of biomass powder material, 0.5-5 parts of hydroxypropyl methylcellulose, 8-20 parts of lubricant, 0.8-2.5 parts of stearic acid and 20-30 parts of water. According to the porous ceramics, the biomass powder material is adopted as the pore former, and meanwhile, the powder coal is used for assisting pore forming, so that the porosity of the ceramic product is increased by 10% to 15% compared with that of the traditional technologies.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a porous ceramic using biomass powder as a pore-forming agent. Background technique [0002] In ceramic products, especially ceramic plates, the porosity has a great influence on the product performance. Products with high porosity have high air permeability, high thermal stability, and low density, which are suitable for the production of ceramic heaters. heating parts. At the same time, in the traditional ceramic production process, paraffin wax is often used as lubricant, which is easy to pollute the environment when fired at high temperature. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, meet the actual needs, and provide a porous ceramic using biomass powder as a pore-forming agent. [0004] In order to realize the purpose of the present invention, the technical scheme adopted in the present inv...
