Application Of Titanium - Application Of Titanium Compounds

Important titanium compounds include titanium dioxide (TiO2), titanium tetrachloride (TiCl4), and barium metatitanate (BaTiO3).
Pure titanium dioxide is a white powder and an excellent white pigment, with the trade name "titanium dioxide". It combines the covering performance of lead white (PbCO3) and the durability of zinc white (ZnO). Therefore, people often add titanium dioxide to paint to make high-grade white paint.
In the papermaking industry, it is added as a filler to the paper pulp.
As a matting agent for artificial fibers in the textile industry; As an additive in the glass, ceramic, and enamel industries to improve their performance; Used as a catalyst in many chemical reactions. In today's rapidly developing chemical industry, titanium dioxide and titanium based compounds, as fine chemical products, have high added value and promising prospects.
Titanium tetrachloride is a colorless liquid; Melting point 250K, boiling point 409K, with a pungent odor. It is highly susceptible to hydrolysis in water or humid air, emitting a large amount of white smoke.
TiCl4+3H2O=H2TiO3+4HCl
Therefore, TiCl4 is used as an artificial smoke agent in military, especially in maritime warfare. In agriculture, people use thick fog formed by TiCl4 to reduce the loss of ground heat at night and protect vegetables and crops from the harm of severe cold and frost.
Melting TiO2 and BaCO3 together to obtain 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. When its crystal is compressed, it generates current, which changes its shape when it is electrified. People place it in ultrasound, and when it is pressed, it generates an electric current. By measuring the strength of the current, the strength of the ultrasound can be measured. It is used in almost all ultrasonic instruments. With the development and utilization of titanium salts, they are increasingly being used to manufacture nonlinear components, dielectric amplifiers, electronic computer memory components, micro capacitors, electroplating materials, aviation materials, strong magnetism, semiconductor materials, optical instruments, reagents, etc.
The excellent properties of titanium, titanium alloys, and titanium compounds make them urgently needed by humans. However, the high production cost limits the application. I believe that in the near future, with the continuous improvement and enhancement of titanium smelting technology, the application of titanium, titanium alloys, and titanium compounds will be further developed.
The corrosion resistance of titanium. Zirconium is a type of material used in the atomic energy industry and as a corrosion-resistant chemical material under high temperature and pressure, but its activity in solution is second only to sodium. Adding active zirconium nitrate solution to titanium hydroxide solution will result in titanium rejecting zirconium nitrate. Moreover, the density of titanium hydroxide is lower than that of zirconium nitrate, but it can still maintain clear layering and keep zirconium nitrate in the upper layer, which proves the corrosion resistance of titanium.
According to the experiment, titanium will not corrode after being placed on the seabed for 20-50 years.
