Possess the highest melting point and the lowest vapour pressure. Excellent material for the technique of the vacuum and for the similar domains. Anti-corrosif towards a lot of acids, construction of rectifiers, switches and contacteurs, of ovens with high temperatures heating resistances and screens reflectors and used for the reprocessing of the waste of fuels of nuclear reactors.
