Titanium dioxide (TiO₂) is a high-purity inorganic compound known for its exceptional optical, chemical, and UV-blocking properties. It is widely used in pigments, coatings, plastics, cosmetics, and photovoltaic applications. Due to its superior whiteness, high refractive index, and excellent stability, titanium dioxide plays a crucial role in precision engineering, environmental solutions, and advanced industrial materials.
Product Overview
Titanium dioxide (TiO2), also known as titanium(IV) oxide, is widely used across various industries, particularly as a pigment, where it is commonly referred to as "titanium white" or "pigment white 6." Its excellent light scattering properties make it an ideal material for applications requiring white opacity and brightness. Common sources of TiO2 include ilmenite, rutile, and anatase.
