Electron-beam vaporization

Rhodium and platinum metals can be more conveniently vaporized with electron-beam vaporization source, in a stainless steel reactor, starting from metal powders deposited into a graphite crucible. 

The ionization of the gas can be achieved by electron beam vaporization [208], hollow cathode discharge [209, 210], glow discharge [34, 192], arc discharge [36], or glow discharge in a parallel magnetic field [33].
