What are the performance and application characteristics of tin oxide ceramics

       Tin oxide (SnO2) ceramic is a white powder with a melting point of 1625 degrees Celsius and a thermal conductivity of 30.5W.m-1.K-1. It is a rutile structure with good physical and chemical stability, corrosion resistance and long working life. One of the most important materials for gas sensors. Tin oxide is difficult to sinter. When used as a gas sensor, the surface of the sintered product is porous, the detection of gas is reversible, the adsorption capacity is strong, and the desorption (desorption) time is short. It is very sensitive to the concentration changes of various trace gases (such as city gas, liquefied petroleum gas, natural gas, hydrogen, carbon monoxide, carbon dioxide, acetone, methane, etc.) obvious. It is a high-quality gas-sensitive material with a very wide range of uses.
