Detailed Description

Rhodium belongs to platinum group metals,it is the highest in electrical and thermal conductivity.It is silvery- white and has a very reflective surface.Rhodium is very hard,durable,and highly resistant to corrosion.It is harder and has a higher melting point than both platinum and palladium,making it a useful hardening element in alloying. Rhodium Powder Purity 99.95% Appearance powder Color Grey - black Density 12.41g/cm3 Melting point 1966 °C Boiling point 3695°C Vickers Hardness 120 Inner Packing by vacuum bag Outter Packing by vacuum bag,250g/bag, 1000g/bag,2000g/bag Min trial order 250grams Applications 1. The majority of rhodium is used as a catalyst in catalytic converters. It is also used to catalyze industrial processes. 2. It is a hard silvery-white metal,also used in the jewelry industry, used as a hardening agent in alloys with Platinum,classified as a transition metal from the platinum group, to produce a reflective white surface in a process called rhodium flashing. It is also used as a coating for sterling silver to reduce the chance of tarnishing. Plated rhodium is sometimes used for optical instruments. 3.It is also used in some alloys containing platinum and palladium for hardening and to provide increased corrosion resistance. 4.Alloyed with Platinum to make heavy duty electrical contacts such as high performance 5.It can also be used as an electrical contact material.
