Important titanium compounds are: titanium dioxide (TiO2), titanium tetrachloride (TiCl4), barium metatitanate (BaTiO3).
Pure titanium dioxide is a white powder, an excellent white pigment, and the trade name is "titanium dioxide". It has both the covering properties of lead white (PbCO3) and the lasting properties of zinc white (ZnO). Therefore, people often add titanium dioxide to paint to make high-grade white paint; in the paper industry, it is added as a filler to paper pulp; in the textile industry
As a matting agent for man-made fibers; as an additive in the glass, ceramic, and enamel industries to improve its performance; as a catalyst in many chemical reactions. With the increasing development of the chemical industry today, titanium dioxide and titanium compounds, as fine chemical products, have high added value and very attractive prospects.
Titanium tetrachloride is a colorless liquid; it has a melting point of 250K, a boiling point of 409K, and a pungent odor. It is easily hydrolyzed in water or humid air and emits a lot of white smoke.
TiCl4+3H2O = H2TiO3+4HCl
Therefore, TiCl4 is used as an artificial aerosol in the military, but it is used in marine warfare. In agriculture, people use TiCl4 to form dense fog on the ground to reduce the heat loss from the ground at night and protect vegetables and crops from severe cold and frost.
Melt TiO2 and BaCO3 together to prepare barium metatitanate:
TiO2+BaCO3 = BaTiO3 + CO2
Artificially made BaTiO3 has a high dielectric constant, and capacitors made from it have a larger capacity. More importantly, BaTiO3 has significant "piezoelectric properties". The crystal will generate current when it is pressed. Will change shape. People put it in the ultrasonic wave, and it generates electric current when it is pressed. The strength of the ultrasonic wave can be measured by measuring the current strength. It is used in almost all ultrasonic instruments. With the development and utilization of titanate, it is more and more widely used to manufacture non-linear components, dielectric amplifiers, computer memory components, miniature capacitors, electroplating materials, aviation materials, strong magnetism, semiconductor materials, optical instruments, reagents, etc. .
The excellent properties of titanium, titanium alloys and titanium compounds prompt humans to urgently need them. However, the high production cost limits the application. We believe that in the near future, with the continuous improvement and improvement of titanium smelting technology, the application of titanium, titanium alloys and titanium compounds will be further developed.
Titanium products:
Titanium and titanium alloys are extremely important lightweight structural materials, which have very important application value and broad application prospects in the fields of aviation, aerospace, vehicle engineering, and biomedical engineering.
