LEARN ABOUT RHODIUM
Rhodium is the rarest, most inert and expensive metal in the platinum group, which also includes platinum and palladium. Its atomic number on the periodic table is 45 and its chemical symbol is Rh.
Rhodium is mostly used for catalytic converters. In fact, more than 90% of rhodium sold goes into catalytic converter production. In this context, rhodium works as a catalyst to reduce air pollution produced by engine combustion. Because of its rarity, rhodium is often alloyed with platinum and palladium. It is the best anti-corrosive metal and it also works easily at high temperatures.
In the catalytic converter recycling business, it takes approximately 400 lbs. of honeycomb monolith to extract 1 oz. of rhodium. Each catalytic converter contains approximately 2 lbs. of honeycomb monolith, which means that precious metal refiners need at least 200 catalytic converters to extract 1 oz. of rhodium.
Only the most advanced technology (from crushing to sampling) can help precious metal refiners determine the amount of rhodium contained in a honeycomb monolith with maximum precision. As a leader in catalytic converter recycling, PMR is proud to provide this high-quality service.
