Materials expand the uses of titanium: pigments, additives and coatings.
Titanium dioxide is the most commonly used titanium compound.
About 95% of the titanium ore mined from the earth's surface is sent to be refined into titanium dioxide (TiO2), commonly known as titanium dioxide (powder), which is an ultra-white and durable pigment with stable properties, no toxicity and good hiding power. It is often used to make paints, paper, toothpaste and plastics, and it is also the main component of Likebao. Titanium dioxide is also used as an opacifier for cement, precious stones and papermaking, and as a reinforcing agent for graphite composite fishing rods and golf clubs.
Powdered titanium dioxide is chemically inert, does not fade in the sun and is very opaque: it is these characteristics that make it bring gorgeous pure white to the gray or brown chemicals used to make household plastics. In nature, compound titanium dioxide can be found in anatase, brookite and rutile.
The coating made of titanium dioxide can resist high temperature, slightly prevent dust accumulation and resist the influence of marine environment. The refractive index of pure titanium dioxide is very high, and its light dispersion ability is higher than that of diamond.
Titanium dioxide is not only an important pigment, but also can absorb ultraviolet rays and can be used in sunscreen cosmetics. Nano-titanium dioxide can also absorb ultraviolet rays, can be made into photocatalyst products, and has the functions of deodorization, sterilization and disinfection.
Recently, it has also been used in air purifiers (filter coatings) and films attached to building windows. When this film comes into contact with ultraviolet rays (solar or artificial) or moisture in the air, it will produce highly active redox substances, such as hydroxyl groups, which can purify the air or keep the window surface clean.
Titanium is also used in automobiles, especially racing cars (automobiles or motorcycles). Reducing weight without losing strength and rigidity is extremely important in this field. Generally speaking, titanium metal is too expensive for the general public to find a market, so its main market is high-end products, especially competitive/high-performance markets. The latest Corvette sports car can be equipped with titanium exhaust system. Google Books-Titanium
