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. The final product is tantalum ingots, the parameters of which are given in the table:
| Make | Ta, not less than,% | Parameters of the ingot, mm | Impurities, no more than,% |
