Precious Metals in High Temperature Applications - The Cause of Damage and its Avoidance

Abstract:

The broad application of platinum and platinum alloys results from their excellent high temperature mechanical properties as well as their near-perfect oxidation resistance and their outstanding resistance to corrosive attack by metal oxide melts such as fluxing agents. However, a few basic rules must be adhered to if platinum devices are to give satisfactory service. Platinum is susceptible to “platinum poisons” and other impurities. These “poisons”, the reasons for their corrosive effects, and techniques for minimizing or eliminating their influence are outlined.
