Titanium Dioxide

Titanium dioxide has the properties of a semiconductor, its conductivity rapidly increases with temperature, and it is also very sensitive to hypoxia. For example, rutile type titanium dioxide is still an electrical insulator at 20 ℃, but when heated to 420 ℃, its conductivity increases by 107 times. Slightly reducing the oxygen content will have a special impact on its conductivity. According to the chemical composition, the conductivity of titanium dioxide (TiO2) is less than 10-10s/cm, while the conductivity of TiO2 1.9995 is as high as 10-1s/cm. The dielectric constant and semiconductor properties of rutile type titanium dioxide are very important for the electronic industry, which utilizes these characteristics to produce electronic components such as ceramic capacitors.

Although titanium dioxide has hydrophilicity, its hygroscopicity is not very strong, and the rutile type is relatively small compared to the anatase type.The hygroscopicity of titanium dioxide is related to its surface area, which is large and has high hygroscopicity.The hygroscopicity of titanium dioxide is also related to surface treatment and properties.
