Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a composite ceramic material. Background technique [0002] High specific surface area ceramics (also known as porous ceramics) are ceramic materials with a large number of penetrating and non-penetrating three-dimensional porous structures. , corrosion resistance, wear resistance, good biocompatibility, high specific strength, etc.) and pore characteristics (such as: low density, good thermal insulation, high specific surface area, low dielectric constant, good permeability, etc.) are effectively combined. At present, ceramics with high specific surface area have been widely used as filter materials, thermal insulation materials, artificial bone materials, electrode materials and catalyst carriers in many fields such as purification and filtration, aerospace, biomedicine, electronic devices, energy and chemical industry. Traditional composite ceramic materials, the ...
