Titanium Dioxide An Overview of Melting Points and Manufacturers

Titanium dioxide (TiO₂) is one of the most widely used inorganic compounds, renowned for its brilliance and opacity. Commonly utilized as a white pigment in various industries, it is also employed in applications ranging from sunscreen formulations to food coloring and even in semiconductor devices. One of the key physical properties of titanium dioxide that is critical for its application is its melting point, which can significantly affect processing and manufacturing methods. Understanding the melting point of titanium dioxide and the leading manufacturers in this sector can provide valuable insights into its industrial utilization.

Melting Point of Titanium Dioxide

Above all, titanium dioxide exists in several crystalline forms, mainly based on its polymorphic structure rutile, anatase, and brookite. The melting point of titanium dioxide varies based on its crystalline form, but it generally ranges from approximately 1,800°C (3,272°F) for rutile to around 1,830°C (3,336°F) for anatase. These high melting points underline the thermal stability and robustness of titanium dioxide, making it an ideal candidate for high-temperature applications.

Due to its high melting point, titanium dioxide can maintain structural integrity in extreme conditions, yielding consistent performance in both automotive coatings and industrial paints. The pigmentation and reflective properties are enhanced when processed at high temperatures, impacting the formulation's final performance and longevity.

A range of manufacturers worldwide specializes in the production of titanium dioxide, each contributing to the market with different formulations and qualities. Industry leaders such as DuPont, Tronox, Huntsman, and Cristal (now part of Tasnee) dominate the titanium dioxide market. Understanding their production processes and the grades they offer can help businesses select the most appropriate variant for their applications.
