An inorganic compound with excellent properties and widely used as a white pigment

Titanium oxide is an insoluble inorganic compound produced from titanium ore, which is widely distributed on the earth. It is widely used as a white pigment because of its high refractive index, excellent whiteness, hiding power, color forming power, and dispersibility. It also has properties as a photocatalyst and is used in various fields such as UV protection, self-cleaning, and photohydrophilization.

TiO2

・Titanium oxide has two crystal structures: rutile type and anatase type, each with different physical properties and uses.
-Rutile type has a high refractive index and excellent hiding power and coloring power, so it is used for pigments such as paints and inks.
・Refractive index: higher than diamond
・Coloring power: 6 times that of zinc white, 15 times that of lead white
・Hiding power: 6 to 7 times that of zinc white (highest among white pigments)
-Anatase type has high photocatalytic activity, so it is used for photocatalytic purposes and as an additive for electrophotographic toner.
・It dissolves in hydrofluoric acid, hot concentrated sulfuric acid, and molten alkali salts, but does not dissolve in other acids, alkalis, water, or organic solvents.
