Rhenium Wikipedia

However, rhenium oxide Re 2 O 7 has poor stability (sublimes at ~360 °C) and therefore is removed during the discharge. Rhenium has a high melting point and a low vapor pressure similar to tantalum and tungsten. Therefore, rhenium filaments exhibit a higher stability if the filament is operated not in vacuum, but in oxygencontaining atmosphere.
