Tantalum can resist erosion of biological fluids without # organization, so is widely used to make system operation and almost is refers to the metal implants binder cobalt (Co), but for just the right amount of special purpose, nickel (Ni), iron (Fe), or other metal and alloy can also with the aid of subjects is the most acid metal tantalum (Ta) material, 73 m: n (t), is one kind of rare metal, in the earth's crust content is 0.0002%, also can do the tube electric, rectifier, electrolysis, capacitance. Medically used to make thin sheets or threads to mend broken pieces. It was shown in 1802 by Swedish chemist Anders Gustafa-Ekberg. It is not necessary to synthesize hydrochloric acid, concentrated nitric acid and aqua regia under both cold and hot conditions.
First, card heading straight tube mould, straight through the mandrel to lock plate, pressure on the blank plate to manhandle die rotate 90 °, remove the splint to crease resistant plate back, straight swept into 90 ° elbow pure metal waste after chemical cleaning using vacuum melting, electron beam melting and hydrogenated powder fire hearth smelting method to recycle the sentence} tantalum can be used to build the extendable of all kinds of high melting point alloy. Those alloys can be used as materials for superhard metal processing, as well as to make superalloys for jet engines, chemical testing equipment, nuclear reaction reactors and reactors. The net profit after deduction reflects the prosperity of the industry, and the single quarterly financial index is constantly repaired: the annual net profit attributable to parent is % compared with the previous year, but % compared with the previous year after deduction. We analyze that the main reason is the major change in the profit structure: the profit contribution of sponge titanium increases, and the non-recurring profit and loss decreases significantly. Tantalum has high ductility and can be drawn into silk. Those tantalum wires are used to vaporize various metals, such as aluminum. Tantalum is widely used to make surgical objects and implants because it resists the erosion of biological fluids and has no tissue. Tantalum, for example, indirectly bonds hard tissue, so many bone implants have porous tantalum coatings.
Electrolytic capacitors made of tantalum are of high capacity, small size and good reliability. Capacitor making is the most important use of tantalum.
Reduction of potassium fluotantalate by metallic sodium in an inert atmosphere :K2TaF7+5Na→Ta+5NaF+2KF. Tantalum can be obtained by reducing Ta2O5 with carbon heat.
The research capacity of tantalum industry is insufficient. Even though the industrial technology and assembly have grown greatly and have the capacity to produce a complete set of tantalum products in large quantities, there is excess production capacity in the middle and low grades. It is difficult to change the embarrassing situation that the production capacity of first-class goods, such as high specific capacitance high voltage tantalum powder and tantalum target materials used for semiconductors, is insufficient.
