Titanium dioxide is the ceramic oxide of titanium characterized by the chemical formula TiO2. This non-toxic material, at a powdered status, is the most widespread white pigment in the world. As a ceramic, it has rather limited applications due to its poor mechanical characteristics. Properties appreciated in the industrial field are: the low coefficient of friction, dielectric strength and sufficient mechanical and wear resistance. Titanium dioxide is normally yellow-brown and is a popular material in the yarn guide sector for textile machines. The not extremely high hardness of this ceramic allows an easier finishing, allowing to obtain very shiny and smooth surfaces for the most delicate synthetic fibers. In addition to the yellow-brown color, there is also the black color variant Ti2O3, titanium trioxide or antistatic titanium.
The antistatic titanium is a reduced form that makes the semiconducting ceramic ideal to work in those environments where electrostatic charges are a problem. Therefore, this ceramic oxide is irreplaceable in certain environments.
TECHNICAL DATA SHEET: TITANIUM OXIDE
Titanium oxide is used in many fields thanks to a series of chemical-physical properties that make this material suitable for various applications.
Its main features are:
- Low coefficient of friction
- Good thermal conductivity
- Good corrosion resistance in both acidic and alkaline environments
- Sufficient mechanical characteristics
- Excellent dielectric properties in the form of dioxide (TiO2)
- Electric conductivity in the reduced form of antistatic titanium (Ti2O3)
The negative characteristics are the poor mechanical properties.
