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, is considered to be in the world today a white pigment with the best performance.
Titanium white has strong adhesion and is not easy to change chemically. It will always be white. It is widely used in coatings, plastics, paper, printing inks, chemical fibers, rubber, cosmetics, and other industries.
Its melting point Very high, it is also used to make refractory glass, glaze, enamel, clay, high-temperature resistant laboratory utensils, etc. At the same time, titanium dioxide has a good UV shielding effect and is often incorporated into textile fibers as a sunscreen.
Ultra-fine titanium dioxide powder is also added to sunscreen cream to make sunscreen cosmetics.
Titanium dioxide can be extracted from rutile by acid decomposition, or from titanium tetrachloride. Titanium dioxide has stable properties and is widely used as a white pigment in paints. It has good hiding power and is similar to lead white, but unlike lead white, it will turn black; it has the same durability as zinc white.
Titanium dioxide is also used as a matting agent for enamel, which can produce a very bright, hard, and acid-resistant enamel glaze finish.
Titanium dioxide is generally divided into anatase type (Anatase, referred to as A-type) and rutile type (Rutile, referred to as R type). What is the difference between A-type and R type TiO2? Click here to know more. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3918909/
