    Microwave sintering is different from the traditional method of heat transfer through conduction, radiation and convection mechanism It uses the special wave band of microwave equipment to couple with the basic structure of the material to generate heat, so that the whole material is heated to the sintering temperature to achieve densification Compared with the traditional sintering technology, microwave sintering has many outstanding advantages: 1 Microwave sintering can convert the energy of electromagnetic wave into the energy of material molecules very quickly, so that the material can be heated at the same time inside and outside, so that the internal temperature gradient of the material is very small, and the internal thermal stress of the material is reduced to Zui low, so it can effectively alleviate the cracking and deformation of the material in the sintering process 2 Microwave sintering can significantly reduce the sintering temperature, and because of the fast heating rate, the sintering cycle is greatly shortened, thus greatly reducing the energy consumption, saving 70% - 90% energy compared with the conventional sintering; moreover, it can significantly reduce the gas consumption of the sintering atmosphere, making the waste and waste heat emissions in the sintering process significantly reduced 3 Under the action of microwave electromagnetic energy, the kinetic energy of molecules inside the material increases, the diffusion coefficient increases, and the sintering activation energy decreases, so that the grains are sintered before they grow up, so as to obtain uniform fine grain structure; moreover, the porosity of the material is small, and the pore shape is more smooth than that of traditional sintering, so that the material has better mechanical properties.
