Tantalum — metal steel-gray hue, almost as heavy as gold has a density of 16.6 g/cm3. Pure tantalum is very ductile despite the hardness Due to their high technological and operating characteristics, the wire and the circle of tantalum widely used instrumentation, electrical engineering, heat power engineering, where the production process involves high temperatures I. aggressive environments. The temperature of The melting point 2996 °C, t° boiling point of 5300 °C, the metal at the same time increases the ductility and toughness of the alloys. Up to 1000 °C, its specific strength is higher than heavy tungsten. Tantalum is resistant to oxidation in air at ordinary temperatures. Oxidation starts at 200−300°C. the Tantalum little resistant to alkalis. With hot alkaline solutions, it forms a salt. Feature of this metal is its ability to absorb gases when heated: nitrogen, oxygen, hydrogen, impurities which affect its performance. The so absorbed hydrogen informs metal fragility, Tantalum absorbs nitrogen at 600 °C. the tantalum Nitrite has t° melting 3087 °C. the disadvantages of tantalum is its high cost. This multiple element of the earth’s crust. Mining and production it is associated with a number of difficulties. This is a rather expensive and heavy metal, heavier than gold.


Tantalum semi-finished products produced by powder metallurgy methods. First, get the Fort. Then it is heated and rolled out a special rotary forging machine. According to GOST 18904.6−89 fraction of impurities in pure tantalum should not exceed tenths of a percent. Pure tantalum is ductile enough and can roll out into a fine foil no thicker than 50 microns. Tantalum sheet produced by the method of «hot-cold» deformation. The original mix for the production of sheet and strip is not a square rod billet cross-section, and the workpiece is flat. Laminate sheet has a very smooth surface, it can be made into products of any shape. Production of tantalum tape normalized GOST 15515−70. The minimum thickness of 0.05±0.01 mm downwards. length up to 100 meters. Format tantalum sheets: 500x500 mm to 800x2000 mm with a thickness of 5 mm Tantalum sheets are manufactured in accordance with GOST 492−73 dimensional and random length.


On the valid samples of insignificant defects, the risks, the traces of broach, shrinkage irregularities, which fall within the boundaries specified by the standard deviations. On the cut sheet and the ribbon must not contain foreign inclusions. The surface must be clean, free of cracks, burrs. Rolled in original packaging stored in closed warehouses. It can be transported by any transport. When transporting the semi-finished products must be protected from mechanical damage, moisture, dirt, corrosive substances.


In the dearness of the metal tantalum sheet is often used for cladding. A method was developed for coating of large products — pipes, sheets, large format, jet engine. The tantalum serves as the basis of chemical reactors, parts of heat exchangers in nuclear power. Tantalum of all known materials is the most stable in pairs, molten 133-cesium. Low work function of electrons important in the manufacture of high-power electronic devices, generators, condensers etc. a Chemical resistance of sheet and strip of tantalum is widely used in the manufacturing of corrosion resistant parts for the processing and the pulp and paper industry. This biologically inert metal tantalum Finest band surgeons fasten ligaments, nervous tissue, from sheet made of bone prostheses. Alloys of tantalum indispensable tool for Metalworking. Carbide of tantalum and tungsten (t° melting almost 3900 °C) to produce super-hard alloys «TT», for percussion rotary drilling. Tantalum foil is the basis of electron-beam instruments, mass spectrometers and other similar devices.
