Titanium Dioxide Melting Points and Manufacturers

Titanium dioxide (TiO2) is a versatile compound with a wide range of applications, making it one of the most important industrial minerals. Known for its high refractive index and strong ultraviolet (UV) light absorbing capabilities, TiO2 is commonly used in various sectors including paints, coatings, plastics, paper, and cosmetics. Understanding the properties of titanium dioxide, particularly its melting point, is essential for manufacturers looking to optimize their production processes.

Properties of Titanium Dioxide

Titanium dioxide exists in three different crystalline forms anatase, rutile, and brookite. Among these, rutile is the most stable and commonly used form, while anatase displays unique photocatalytic properties, making it beneficial in applications such as environmental remediation and self-cleaning surfaces. The melting point of titanium dioxide varies depending on the crystalline structure. Generally, rutile has a melting point of about 1,840 degrees Celsius (3,344 degrees Fahrenheit), while anatase melts at approximately 1,800 degrees Celsius (3,272 degrees Fahrenheit). These high melting points make TiO2 suitable for high-temperature applications, such as ceramics and certain types of glass.

Importance of Melting Point in Manufacturing

The melting point is crucial for the manufacturing of titanium dioxide because it directly influences the processing conditions, including temperature control during production and application. In industries such as ceramics and glass, the ability of TiO2 to withstand high temperatures without degrading is vital for product integrity and performance. Additionally, during the synthesis of TiO2 through methods like the sulfate and chloride processes, understanding the thermal behavior of different TiO2 phases helps in optimizing yield and quality.

Manufacturers must also consider the thermal stability of TiO2 during its storage and usage. If the material is exposed to conditions beyond its melting point, it can lead to undesirable changes in its chemical and physical properties, ultimately affecting the end product's performance. Consequently, correct handling and processing of titanium dioxide are fundamental to benefit from its desirable characteristics.
