The essence of the process
Electron beam melting is the most progressive method of obtaining such refractory metals as tantalum. The process is carried out in a vacuum with a significant overheating of the tantalum melt. In this case, intensive evaporation of metal from the surface of the bath with a liquid melt occurs. Depending on the electronic structure of the metal, the evaporation intensity is different, and therefore during the electron-beam melting evaporation of individual elements occurs, which are subsequently separated. This ensures a high degree of chemical purity of the final product. Volatility is determined by the vapor pressure of a chemical element above the melt, the concentration of the melt and its current temperature. Then follows the rolling of semi-finished products to obtain the final product — sheet and / or foil. Parameters of finished products are given in the table:
| Make | Ta, not less than,% | Sheet / foil parameters, mm | Impurities, no more than,% |
| ELP-1 | 99.9 | Thickness: sheet — 0,1… 10 mm, width 100… 150 mm, length 300 mm and more; foil — 0,05… 2 mm, width 50… 150 mm, length up to 300 mm |
