Electron beam fusion/refining machine for refractory metals (niobium Nb, tantalum Ta)

The electron beam facility for melting/refining is applied to produce high purity metals and alloys to be used in high-tech industries.

The melting is carried out in high vacuum inside a water-cooled copper crystallization vessel thus ensuring impurity free substance.

The vapors of metals generated while refining are deposited on condensation screens and are recyclable.

The hardware is manufactured on request under approved Technical assignment. Any parameters can be changed at your convenience.

Benefits of electron beam technology

• Heat emission in metal and scrap that ensures high efficiency of the process.
• No contact between metal and crucible material thus avoiding impurities.
• The process takes place in high vacuum so the metal is not oxidizing.
• High energy concentration up to 108W/cm2 impossible to reach with other heating methods.
