Abstract
The invention relates to a preparation method of a high-temperature-resistant thermal-shock-resistance ceramic material, and belongs to the technical field of high temperature resistance material. Thepreparation method comprises following steps: sugarcane is taken as a raw material, is crushed, and is mixed with aluminium powder and magnesium powder so as to obtain a mixture; rice husk is taken as a raw material, and is subjected to pyrolysis, an obtained rice husk pyrolyzate and an alkali solution are mixed for reaction, after reaction, an obtained reacted solution and the mixture are subjected to blending reaction, wherein in the reaction process, carbon dioxide is introduced for aeration, so that a colloid product is obtained; and then the colloid product is subjected to drying charingand high temperature sintering so as to obtain the high-temperature-resistant thermal-shock-resistance ceramic material. The high-temperature-resistant thermal-shock-resistance ceramic material is excellent in high temperature resistance and thermal shock resistance, and is promising in application prospect.
Description
technical field [0001] The invention relates to a method for preparing a high-temperature-resistant and thermal-shock-resistant ceramic material, which belongs to the technical field of high-temperature-resistant material preparation. Background technique [0002] Ceramics, in terms of their materials, are divided into pottery, stoneware and porcelain, also commonly known as pottery, stoneware and porcelain. Ceramics is an advanced material state developed by natural materials through the practice of human production. Its physical and chemical properties are outstanding: its surface decoration techniques are rich, acid rain resistant, and has a good self-cleaning function. The surface glaze color has a translucent glass texture; Thousands of years of labor practice have rich molding and manufacturing techniques. [0003] With the development of society, ceramics occupy an important position in many fields and are recognized by many consumers. The use environment of ceramics...
