Use of titanium powder

Titanium cylinder, the quality is "No. 2 grade"

Titanium is an alloying element of steel (iron titanium). Titanium will reduce the grain size of steel. At the same time, titanium as a deoxidizer will reduce the oxygen content of steel; adding titanium to stainless steel will reduce the carbon content.

Titanium is often alloyed with other metals, such as aluminum (improved grain size), vanadium, copper (hardened), magnesium, and molybdenum.

Titanium mechanical products (sheets, plates, tubes, wires, forgings, castings) have applications in industry, aerospace, leisure and emerging markets.

Titanium powder is used in the manufacture of pyrotechnics to provide bright combustion particles.

Pigments, additives and coatings

Titanium dioxide is the most commonly used titanium compound

About 95% of the titanium ore mined from the surface of the earth is sent to be refined into titanium dioxide (TiO2), an ultra-white long-lasting pigment that is used to make paint, paper, toothpaste an plastics.Titanium dioxide is also used in cement, gemstones, paper-making sunscreens, graphite composite fishing rods, and golf clubs.

Powdered TiO2 is chemically inert, does not fade in the sun, and is very opaque: these properties make it possible to bring a brilliant pure white color to the gray or brown chemicals used in the manufacture of household plastics.

In nature, the compound of titanium dioxide can be found in several minerals such as anatase, brookite and rutile.

 Coatings made of titanium dioxide can withstand high temperatures, slightly prevent the accumulation of dust and dirt, and withstand the impact of the marine environment.

The refractive index of pure titanium dioxide is very high, and the optical dispersion ability is higher than that of diamond.

In addition to being a very important pigment, sunscreen oil also uses titanium dioxide, because it can protect the skin by itself.

Recently, it has also been used in air purifiers (filter coatings), and films attached to windows of buildings. This kind of film will generate a height when exposed to ultraviolet rays (sun or artificial) or moisture in the air.

 Active redox species, such as hydroxyl, can purify the air or keep the window surface clean.

Space Navigation and Navigation

 Due to its high tensile strength-density ratio, excellent corrosion resistance, fatigue resistance, crack resistance and ability to withstand moderate high temperatures without creep, titanium alloys are used in aircraft, armor plates, and naval ships. , Spacecraft and missiles. In these applications, titanium alloys made of aluminum, vanadium and other elements are used to manufacture various components, including key structural components, firewalls, landing gear, exhaust pipes (helicopters) and hydraulic systems. In fact, about two-thirds of titanium production is used to make spacecraft engines and structures. The SR-71 "Black Bird" was the first body to widely use titanium in its architecture, paving the way for the application of titanium in modern military and commercial bodies. It is estimated that 59 tons of titanium are used to produce Boeing 777, 44 tons for Boeing 747, 18 tons for Boeing 737, 32 tons for Airbus A340, 18 tons for Airbus A330, and 12 tons for Airbus A320. Airbus A380 may use 146 tons, of which the engine requires 26 tons. In engine applications, titanium is used in rotors, compressor blades, hydraulic system components and nacelles. Among titanium alloys used in aviation applications, titanium-6 aluminum-4 vanadium accounts for almost 50%.

industry

The chemical and petrochemical fields require welding titanium pipes and processing equipment (heat exchangers, tanks, processing vessels, valves), mainly due to the corrosion resistance of titanium.

In-well and nickel hydrometallurgical applications require specific alloys, such as titanium βC, because of the need for high strength, high corrosion resistance, or both.

Titanium is used in some production equipment in the paper industry that faces corrosive media, including sodium hypochlorite or wet chlorine (for bleaching).

Other applications include: ultrasonic welding, wave soldering and sputtering targets.

Titanium tetrachloride (TiCl4) is a colorless liquid. It is an important intermediate in the production of titanium dioxide. It can be used to produce Ziegler-Natta catalysts and to make iridium-coated glass.

There will be dense smoke in the air, so titanium tetrachloride can be used to make smoke screens.
