Titanium dioxide (TiO2) is an important inorganic chemical product, which has important applications in coatings, inks, paper, plastics, chemicals, ceramics and other industries. The main component of titanium dioxide is a white pigment of titanium dioxide (TiO2). The molecular formula is TiO2, which is a polycrystalline compound whose particles are regularly arranged and have a lattice structure. Titanium dioxide has the lowest relative density. The production process of titanium dioxide has two routes of sulfuric acid method and chlorination method.
Titanium dioxide is extremely chemically stable and is an acidic amphoteric oxide. It does not react with other elements and compounds at room temperature, and has no effect on oxygen,nitrogen, hydrogen sulfide, carbon dioxide . It is insoluble in water, fat, insoluble in dilute acid and inorganic acid and alkali, and soluble in hydrogen only. Fluoric acid. However, under the action of light, titanium dioxide can undergo continuous redox reaction and has photochemical activity. This photochemical activity is particularly evident in the case of anatase titanium dioxide under ultraviolet irradiation. This property makes titanium dioxide a photosensitive oxidation catalyst for certain inorganic compounds and a photoreduction catalyst for certain organic compounds.
Emergency treatment: Isolation of contaminated areas and restrictions on access. It is recommended that emergency personnel wear a dust mask (full face mask) and wear general work clothes. Avoid dusting, carefully sweep it, place it in a bag and transfer it to a safe place. If there is a lot of leakage, cover it with plastic cloth and canvas. Collected for recycling or transported to a waste disposal site for disposal.
Titanium dioxide is widely used in various structural surface coatings, paper coatings and fillers, plastics and elastomers. Other uses include ceramics, glass, catalysts, coated fabrics, printing inks, roofing granules and fluxes.
 

1) In paint industry, It is used as white pigment and glaze of porcelain. 
2) It can also be used as coating and filling in paper-making industry to help paper to be printable and opaque. 
3) In metallurgical industry, it can be used to make spongy titanium, alloy of titanium and iron and hard alloy, etc. 
4) It can also be used to make nonconductor, electric welding rod and porcelain enamel. 
5) It can also be used in synthetic fibre, plastic, rubber, printing, dying, cosmetics and food additives.
