ABSTRACT:
The invention relates to a novel palladium-based alloy.
This palladium-based alloy comprises at least one additional element selected from indium, bismuth, silver and copper, in an amount sufficient to impart an acceptable resistance to corrosion by molten glass, preferably being essentially equivalent to that of platinum-rhodium 10% alloys.
An alloy of this type can be used in the glass industry for making components which come into contact with molten glass, which preferably essentially contains no oxides less stable than the oxide of the additional element, such as lead oxide, because is has an excellent resistance to corrosion by molten glass and is less expensive than the platinum-rhodium 10% alloy normally used. Moreover, by the addition of at least one element selected from platinum (0-50% by weight), rhodium (0-20% by weight), iridium (0-20% by weight), ruthenium (0-20% by weight) and tin (0-20%), the mechanical strength at high temperature, especially the creep strength, is significantly improved.
