Samarium can be evaporated from a tantalum boat or an Al2O3 crucible with either a shielded tantalum box heater or a tungsten wire basket heater. Samarium begins to evaporate around 575 C (where its vapor pressure is 104 Torr). Higher temperatures will increase the deposition rate. DC sputtering is also an option.Samarium does oxidize so both the pellets/target and the deposited films should be protected from oxidation as much as possible by handling and storing it under inert gas like Ar. We ship the material in a mineral oil to protect the material from oxidation and that must be cleaned off prior to use. It is strongly advised to consult the MSDS prior to working with samarium. Samarium can be evaporated from a tantalum boat or an Al2O3 crucible with either a shielded tantalum box heater or a tungsten wire basket heater. Samarium evaporates around 575 deg C (where its vapor pressure is 104 Torr). Higher temperatures will increase the deposition rate. DC sputtering is also an option.
