Titanium compounds and uses

Important titanium compounds include: titanium dioxide (TiO2), titanium tetrachloride (TiCl4), partial barium titanate (BaTiO3).

Pure titanium dioxide is white powder, is an excellent white pigment, trade name "Titanium White." It combines white lead (PbCO3) covering performance and zinc white (ZnO) lasting performance. Therefore, it is often added to grade 2 titanium wire dioxide in the paint, white paint made from advanced; in the paper industry as a filler added to the pulp; the textile industry as rayon matting agent; on glass, ceramic, enamel industry as additives to improve their performance; used as a catalyst in many chemical reactions. In today's growing chemical industry, titanium dioxide and titanium compounds as fine chemical products, with high added value, the prospects are very attractive. Titanium tetrachloride is a colorless liquid; mp 250K, the boiling point of 409K, there are prepared odorous. It is in water or moist air are easily hydrolyzed, smoke a lot of white smoke.

TiCl4 + 3H2O == H2TiO3 + 4HCl

Therefore TiCl4 in the military as artificial aerosols, which are still used in marine warfare. In agriculture, the formation of fog covered it with TiCl4 ground floor at night to reduce heat loss, protect vegetables and crops from cold, frost damage.

The TiO2 and BaCO3 obtained partial melt together barium titanate:

TiO2 + BaCO3 == BaTiO3 ten CO2 & shy;

Artificial obtained BaTiO3 having a high dielectric constant, the capacitor made therefrom has a larger capacity, more importantly BaTiO3 significant "piezoelectric properties", the crystal under pressure will produce electricity, a power, and changes shape. People put it in the ultrasound, which will produce a current pressure, the intensity can be measured by measuring the current intensity of the ultrasound. Almost all of the ultrasonic instrument should be used to it. With the development and utilization of titanates, which more and more widely used to make non-linear element, an amplifier medium, computer memory device, the mini-capacitors, electroplating materials, aerospace materials, magnetic, semiconductor materials, optical instruments, reagents, etc. .

Titanium, thin titanium sheet alloys and titanium compounds excellent performance prompted urgent human needs them. However, high production costs, so the application is limited. We believe that in the near future, with the titanium smelting technology continues to improve and enhance the use of compounds of titanium, titanium and titanium will be greater development.
