The chemistry of the extremely stable Titanium(IV) oxide, is a partial acid 117-81-7 sexual oxide. Under normal temperature is not with other almost elements and compounds, responding to oxygen, ammonia, hydrogen, carbon dioxide, nitrogen, and sulfur dioxide don't help, insoluble in water, fat, also not soluble in dilute acids and inorganic acid, alkali, only soluble in hydrofluoric acid. But in light effect, Titanium(IV) oxide can happen continuous REDOX reaction, have photochemical activity.
This kind of photochemical activity, uv rays sharp titanium type of titanium dioxide particularly obvious, this nature made of Titanium(IV) oxide even some inorganic compounds photosensitive oxidation catalyst, is certain 1345-05-7 organic compound photosensitive reduction catalysts. Emergency treatment: isolation leakage pollution area, limiting access. Suggest the emergency treatment personnel wear dustproof mask (full cover), wear generally work overalls. Avoid dust, be careful and on, in bag transfer to safety. If large spills with plastic cloth, canvas covered. Collect recovery or shipped to the waste disposal sites. Titanium dioxide (or says Titanium(IV) oxide) widely used in the various types of structure surface coatings, paper coating and packing, plastic and elastomer, and other USES include ceramic, glass, catalyst, coated fabric, printing ink, and shop roof of grain and flux.
According to statistics, 2006 global titanium dioxide demand 471-34-1 of 4.6 million tons, which accounted for 58% of the paint industry, plastic industries accounted for 23%, 10%, other 9% paper. Titanium dioxide can be used titanium iron ore, rutile production, also can use titanium slag production.Titanium dioxide production process has two kinds: namely sulfate process and chloride process, sulfate method than chloride method of technology is simple, can supplies a low and cheaper mineral. Currently about 47% capacity in the world by sulfate process, 53% capacity of chloride process.
