Glass creation accounts for a further three p.c to six p.c of rhodium intake every year. As a consequence of their high melting factors, toughness and resistance to corrosion, rhodium, and platinum might be alloyed to kind vessels that hold and form molten glass.

Rhodium serves to be a catalyst in hydroformylation reactions, a course of action that provides a formyl group in addition to a hydrogen atom to your substrate, generally an alkene.
