Abstract
Official abstract text for this publication.
A tantalum or tantalum alloy which contains pure or substantially pure tantalum and at least one metal element selected from the group consisting of Ru, Rh, Pd, Os, Ir, Pt, Mo, W and Re to form a tantalum alloy that is resistant to aqueous corrosion. The invention also relates to the process of preparing the tantalum alloy.
First claim
Opening claim text (preview).
We claim: 1. A tantalum alloy resistant to aqueous corrosion and consisting essentially of Ta-3W—X, wherein (i) X is at least one of Ru or Pd, and (ii) X is present in an amount of at least 50 ppm and at most 10,000 ppm. 2. The tantalum alloy of claim 1 , wherein X is present in an amount of at least 500 ppm and at most 10,000 ppm. 3. The tantalum alloy of claim 1 , wherein X is present in an amount of at least 500 ppm and at most 5,000 ppm. 4. The tantalum alloy of claim 1 , wherein X is present in an amount of at least 500 ppm and at most 2,000 ppm. 5. The tantalum alloy of claim 1 , wherein X is Ru. 6. The tantalum alloy of claim 1 , wherein X is Pd.
