More info

Tin Dioxide is an inorganic substance with the chemical formula SnO2. It is a white, light yellow, or light gray tetragonal, hexagonal or orthorhombic crystalline powder. The melting point is 1630°C and the boiling point is 1800°C. With a density of 6.95 g/mL at 25 °C, it is also an excellent transparent conductive material. It is the first transparent conductive material put into commercial use. In order to improve its conductivity and stability, it is often doped and used, such as SnO2: Sb, SnO2: F, etc.

High-purity and ultra-high purity Tin Dioxide (SnO2) materials are crucial components for the research, development, and production of advanced technologies which require optimum properties, performance, and quality.

SnO2 is an important semiconductor sensor material with which air sensors have high sensitivity and is widely used in the detection and prediction of a variety of combustible gases, environmental polluting gases, industrial exhaust gases, and harmful gases. Wet-sensitive sensors prepared with SnO2-based materials have been used in improving the indoor environment, precision instruments, and equipment rooms, libraries, art galleries, museums, etc. By doing a certain amount of CoO, Co2O3, Cr2O3, Nb2O5, Ta2O5, etc. in the SnO2, voltage resistors with different resistance values can be made, with a wide range of uses in power systems, electronic lines, household appliances, etc.
Because SnO2 has good permeability to visible light, excellent chemical stability in aqueous solution, and has specific conductivity and reflected infrared radiation characteristics, it is also widely used in the fields of lithium batteries, solar cells, liquid crystal display, optoelectronic devices, transparent conductive electrodes, anti-infrared detection, and protection, etc. SnO2 nanomaterials due to their small size effect, quantum size effect, surface effect, and macroscopic quantum tunneling effect, in the light, thermal, electric, acoustic, magnetic and other macroscopic properties will be significantly changed then the traditional SnO2, so the use of nanomaterials to improve the performance of sensor materials.
