Rutile titanium dioxide is a titanium dioxide (TiO₂) that exists in the rutile crystal form and is one of the main types of titanium dioxide pigments. The following is a detailed introduction to rutile titanium dioxide products:
Basic Information
Chinese Name: Rutile Titanium Dioxide
English Name: Rutile Titanium Dioxide
Main Component: Titanium Dioxide (TiO₂)
Crystal Form: Rutile
Physical and Chemical Properties
Color and Appearance: White powder, particles arranged in rutile structure.
Melting Point and Boiling Point: The melting point is 1850℃ (melting point in air is 1830±15℃, melting point in oxygen-rich environment is 1879℃), and the boiling point is 3200±300℃.
Hardness: According to the Mohs hardness scale, the hardness of rutile titanium dioxide is 6~6.5.
Hygroscopic: Although it is hydrophilic, it is not very hygroscopic, and it is related to its surface area and surface treatment properties.
Chemical Stability: At room temperature, it hardly reacts with other elements and compounds. It is not affected by oxygen, ammonia, nitrogen, hydrogen sulfide, carbon dioxide, sulfur dioxide, etc. It is insoluble in water and fats, and insoluble in dilute acids, inorganic acids, and alkalis. It only dissolves in hydrofluoric acid. However, under the action of light, it can undergo continuous oxidation-reduction reactions and has photochemical activity.
