The effect of adding very small amounts of yttrium and zirconium to platinum alloys has been investigated. The results indicate that a platinum alloy which contains bath elements has a higher recrystallisation temperature and superior mechanical properties than a platinum alloy containing only zirconium. In addition, the platinum alloy which contains both yttrium and zirconium has a stable structure in which regular second phases have been found both in the grains and on the grain boundaries.
