The use of platinum and its alloys, such as 10% rhodium/platinum, is well established in the glass industry. However, their applications often mean high temperature operation of these materials. At high temperatures these materials are weak, subject to creep and to contamination failure. Johnson Matthey has developed a material which is a form of platinum, Zirconia Grain Stabilized (ZGS). The inclusion of zirconia into precious metals restricts the effect of contamination and deformation at high temperatures by resisting grain growth.

ZGS platinum materials offer significantly improved performance over conventional platinum and its alloys.
