Titanium smelting authoritative introduction

With iron, aluminum, like titanium in titanium also showed a positive valence. However, both anatase titanium metal smelting difficult than iron and aluminum smelting. This is not only because of the low levels of anatase titanium, but also because the compounds have to be purified before the smelting of titanium, is more difficult than extracting pure alumina from bauxite. Titanium and lively than iron, titanium positive valence restore it, use a stronger reducing agent than carbon monoxide. How to get elemental titanium grade 5 from titanium smelting it?


After selection of titanium ore enrichment, containing titanium dioxide can get 80% of high titanium slag. The high titanium slag with coke, chlorine were hot, titanium dioxide becomes titanium tetrachloride.


TiO2 + 2C + 2Cl2 TiCl4 + 2CO


The melting point of titanium tetrachloride, are very low boiling point, liquid at room temperature, it is easy to purify. Titanium tetrachloride obtained after purification, purity of 99.9%.


The above reaction is a redox reaction, but the plate titanium valence change in the reaction, that is, the titanium was not reduced. Commonly very active metal (such as sodium or magnesium) as a reducing agent, titanium tetrachloride reduction of titanium. Such as the magnesium metal and titanium tetrachloride at 800 ℃ reaction, can be obtained metallic titanium and magnesium chloride.



Titanium obtained by this method showed a cavernous, called titanium sponge. It baked in an electric furnace made of titanium ingots, for further processing use.

Titanium screws used bike

Titanium gives the impression that "light and hard." Keen lightweight riders tend to have replaced all the screws of titanium alloy plate alloy was satisfied. Titanium give some people the wrong impression, expensive and rare, in fact, titanium is one of the more abundant on earth burial abundant element.
Only because refining alloy production cost is very high, the price was expensive.
Titanium light weight, high strength, and high corrosion resistance of materials, usually used in a special environment.
After the addition of aluminum, vanadium (Li.V) in pure titanium, the alloy strength improved significantly.

Titanium mechanical properties:
Alloy Name Tensile strength (MPa) Endurance (Mpa) Elongation (%) E (GPa)
6Al-4V Ti (TC4) 980 920 14 110

Titanium products advantages:
Light weight, far more than the strength of steel, aluminum, lightweight and can produce high-intensity parts, such as screws class does not rust, titanium rod hardly etched in the general environment.
Riding feeling good, titanium is also used in the shock absorber spring. Now the frame made of titanium are suitable for long ride. Some riders love titanium frame that sense excellent ride. But individuals vary, and some people think that comparison chrome-molybdenum steel, chrome-molybdenum steel frame shock absorption better than titanium frame, riding feeling is better (shape it and chromium molybdenum steel frame than titanium rod for sale frame and thin The stress of the tube to get the increase is also relevant). If processing technology has been further improved titanium tube, there may be riding the same sense and chromium molybdenum steel.

Titanium screws on the bike specifications and use the list (please add correct me):

2 grade titanium on the human body effect

2 grade titanium products by regulating the body current, so that the temperature rise, reaching the spirit of relaxation,medical titanium bar muscle relaxation, improve the effect. Heat would increase muscle relaxation, and stimulate blood flow, increased blood flow helps your body to better eliminate blood substrates and fatigue factor generated by pain.
Because there are a variety of excellent Titanium features many Western young people have chosen to do the carrier to produce titanium wedding ring, with a large diamond,titanium plates makes titanium ring that is a symbol of elegance and rock-solid love.
