As a means of microwave industrial processing, it has been applied in the chemical industry, mainly for nickel hydroxide, zirconium oxide, cobalt oxide, lithium oxide, cobalt oxide, bismuth oxide, (sub) nickel, silicon oxide, antimony oxide, carbonate manganese and other dry chemical products, ceramic materials (including superconducting materials), and graphite sintered products (combustion synthesis), and synthetic chemical used in microwave, microwave-induced catalytic reactions, microwave plasma applications, effectively promoted the development of chemical industry . With the development of economy and science and technology, microwave technology in the chemical industry can be more widely used.
