77891 titanium dioxide

Titanium dioxide, often referred to as TiO2, exists in two primary forms rutile and anatase. Rutile TiO2 is renowned for its exceptional optical properties and higher refractive index, making it the preferred choice for applications requiring maximum brightness and durability. This form of titanium dioxide is characterized by its dense particle structure, providing superior weatherability and resistance to discoloration, essential traits for products exposed to the elements.

The first commercial production of TiO2 began in the early 20th century, using the sulfate process. This method involved reacting ilmenite ore with sulfuric acid to produce titanium sulfate, which was then calcined to obtain titanium dioxide. However, this process had several drawbacks, including high energy consumption, generation of large amounts of waste, and release of harmful gases such as sulfur dioxide. As a result, many factories transitioned to the chloride process, which offers higher purity TiO2 and reduced environmental impact.
