Electrical conductivity: Titanium dioxide has the properties of a semiconductor. Its electrical conductivity increases rapidly with the rise of temperature, and it is also very sensitive to hypoxia. For example, rutile titanium dioxide is still an electrical insulator at 20°C, but when heated to 420°C, its electrical conductivity increases by 107 times. Slightly reducing the oxygen content will have a special impact on its electrical conductivity. According to the chemical composition of titanium dioxide (TiO2), the electrical conductivity is <10-10s/cm, while the electrical conductivity of TiO1.9995 is as high as 10-1s/cm. The dielectric constant and semiconductor properties of rutile titanium dioxide are very important to the electronics industry, which uses the above characteristics to produce electronic components such as ceramic capacitors.
