Further information Description Rhodium metal is silvery white.
Rhodium has a higher melting point and lower density than platinum.
It has a high reflectance and is hard and durable. Upon heating it turns to the oxide when red and at higher temperatures turns back to the element. It is a major component of industrial catalytic systems such as the BP-Monsanto process. Both values are quoted on the Pauling scale.
