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 ingots are made with a diameter of 60… 130 mm and a length of up to 750 mm. Supplied with a machined surface or with a surface partially refined by an electron beam. The mass fraction of impurities (in%) should not exceed the values indicated in the table:
| niobium 0.05 | oxygen 0.01 | sodium 0.0002 | manganese 0.0001 | Tin 0.0001 |
