SnO2 is a widely used sem-iconductor gas-sensing material. Resistance gas sensor made of SiO2 powder has high sensitivity to a variety of reducing gases. It is widely used in the detection and alarm of combustible gases. The combustible gas sensor designed and manufactured by it has the characteristics of high sensitivity, large output signal, high impedance to toxic gas, long life and low cost.

Tin oxide is a very good catalyst and catalyst carrier. It has a strong ability to fully oxidize and has a good effect on the oxidation of organic matter. It can catalyze the fumarate-based reaction and the oxidation of CO.

SnO2 has good permeability to visible light, excellent chemical stability in aqueous solution, and has specific conductivity and characteristics of reflecting infrared radiation. Therefore, it is used in lithium batteries, solar cells, liquid crystal displays, optoelectronic devices, transparent conductive Electrodes, anti-infrared detection protection and other fields are also widely used
