Description

technical field [0001] The invention relates to a ceramic material, in particular to a porous titanium carbide ceramic material and a preparation method thereof. Background technique [0002] Ceramics is the general term for pottery, stoneware and porcelain. Any object made from two different types of clay, clay and china clay, through batching, molding, drying, roasting and other processes can be called ceramics. Traditional ceramics are mainly used for daily necessities and works of art. At present, ceramics have been widely used in construction, chemical industry, aerospace and other fields, and the requirements for ceramic performance are gradually increasing. [0003] Porous ceramics have a series of excellent characteristics, such as light weight, low relative density, high specific strength, high specific area, good permeability, good adsorption, etc. At present, titanium carbide ceramics is one of the development directions of porous ceramics, but the current carboni...
