Description

technical field [0001] The invention belongs to the field of ceramic materials, and in particular relates to a gas-sensitive ceramic material. Background technique [0002] Gas-sensitive ceramic materials refer to ceramics whose electrical conductivity changes with the types of gas molecules they are in contact with. They are mainly used for leak detection, disaster prevention alarms and measurements for different gases. The function of traditional gas-sensing ceramic materials is relatively single, and the scope of application is narrow. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a gas-sensitive ceramic material. [0004] The technical solution of the present invention is: a gas-sensitive ceramic material, which is composed of the following raw materials in weight fractions: 30-37 parts of silicon carbide, 17-20 parts of silicon oxide, 10-17 parts of silicon dioxide, and 2-6 parts of zinc oxide , 1-4 parts of t...
