Titanium dioxide (chemical formula: TiO₂, white solid or powdered amphoteric oxide, molecular weight: 79.9, is a white inorganic pigment with non-toxic, best opacity, best
whiteness and brightness, and is considered to be the world today A white pigment with the best performance. Titanium white has strong adhesion, is not easy to undergo
chemical changes, and is always white. It is widely used in coatings, plastics, papermaking, printing inks, chemical fiber, rubber, cosmetics and other industries. Its melting
point Very high, it is also used to make refractory glass, glaze, enamel, clay, high temperature laboratory utensils, etc.
At the same time, titanium dioxide has a good UV shielding effect, often used as a sunscreen agent in textile fibers, and ultra-fine titanium dioxide powder is also added to
sunscreen creams to make sunscreen cosmetics.
Titanium dioxide can be extracted from rutile by acid decomposition, or from titanium tetrachloride. Titanium dioxide is stable in nature and is widely used as a white pigment
in paints. It has good hiding power and is similar to lead white, but it does not turn black like lead white; it has the same durability as zinc white. Titanium dioxide is
