Pt is the basis.
According to GOST 31290-2005 the chemical composition is given for platinum PlA-2 (ingots) and PLA-2 (in powder), the total content of all impurities is ≤ 0.10%, the total content of Pd + Ir + Rh + Ru ≤ 0.050%. In agreement with the consumer, the number of detectable elements (impurities) can be expanded and their maximum permissible mass fractions determined, as well as the determination of losses during ignition for platinum in powder according to the methods of the manufacturer.
