Chemical properties of titanium plates are relatively active metal

And non-metallic effect can be O2, N2, H2, S , and halogen when heated. But at room temperature , titanium oxide surface dense layer of protective film is easy to generate very thin , can resist strong acid or aqua regia role , showing strong corrosion resistance. Thus, the general metal becomes riddled with acid , alkali, salt solution and titanium are safe and sound .

Almost all of the liquid titanium to dissolve the metal, and a variety of metal forming an alloy . Ti added steel obtained titanium steel tough and elastic. Titanium metal Al, Sb, Be, Cr, Fe , etc. to generate a compound of formula or a metal shim between the compounds .

The same aircraft titanium alloy aircraft heavier than other metal overload passengers than 100 people. Submarine made ​​, both anti- seawater corrosion , but also the deep anti- stress, increase its steel submarine dive depth 80 . Meanwhile , titanium non-magnetic, not mine found , with good anti- guardianship role .

Titanium has a " pro-biotic " ' sex . In the human body , can resist the corrosive and non-toxic secretions , have to adapt to any sterilization method . It is widely used in making medical devices, making artificial hip, knee, shoulder , flank joints, skull , active heart valves , bone clip. When a new packet in the annulus muscle " titanium -bone" , these titanium bone began to maintain the body's normal activities .

Titanium is widely distributed in the body , the content of the normal body weight not exceeding 70kg per 15mg, its role is unclear. However, titanium can stimulate phagocytic cells, the immune system has been proven to enhance this role .

Titanium compounds and uses
Important titanium compounds include: titanium dioxide (TiO2), titanium tetrachloride (TiCl4), partial barium titanate (BaTiO3).

Pure titanium dioxide is a white powder , is an excellent white pigment , trade name " Titanium White ." It combines white lead (PbCO3) covering performance and zinc white (ZnO) lasting performance. Therefore, people often put titanium dioxide added to the paint , white paint made ​​from advanced ; in the paper industry as a filler added to the pulp ; textile industry

Rayon as matting agent ; on glass, ceramic , enamel industry as additives to improve performance ; used as a catalyst in many chemical reactions. In today's growing chemical industry , titanium dioxide and titanium compounds as fine chemical products , with a high added value , the prospects are very attractive.

Titanium tetrachloride is a colorless liquid ; m.p. 250K, the boiling point of 409K, with the laser system odor . It in water or moist air are easily hydrolyzed , emitting a large amount of white smoke.

TiCl43H2O == H2TiO34HCl

So TiCl4 in the military as an artificial aerosols , which are still used in marine warfare .Xinnuo titanium whole distributor In agriculture, people with TiCl4 formation of ground fog , reducing heat loss at night the ground to protect the vegetables and crops from cold, frost damage.

The TiO2 and BaCO3 obtained partial melting together of barium titanate :

TiO2BaCO3 == BaTiO3 ten CO2-

Human prepared BaTiO3 have a high dielectric constant capacitors made ​​from it has a larger capacity, more important is the BaTiO3 having significant " piezoelectric properties ", the crystal produces a current pressure , a power, and will change shape . People put it in the ultrasound , which pressure will produce a current strength can be measured by measuring the current intensity of the ultrasound . Almost all of the ultrasonic instrument to be used in it . With the development and utilization of titanate , which is more widely used to make non-linear components , media amplifiers, computer memory devices , micro- capacitor , electroplating materials , aerospace materials, magnetic, semiconductor materials, optical instruments , reagents, etc. .

Titanium , titanium alloys and titanium compounds excellent performance prompted urgent human needs them Xinnuo medical titanium plates. However, the high cost of production , so that the application is limited. We believe that in the near future, with the titanium smelting technology continues to improve and enhance the application of the compounds of titanium , titanium alloy and titanium will be greater development.
