Mo-Ti members with non-metallic sintering aids

摘要

Boron, oxygen, or a mixture thereof, is used as a sintering aid in sintering Mo-Ti alloys. Compounds formed between these sintering aids and the Mo or Ti have thermal expansion coefficients consistent with that of alloys of Mo and Ti. An hermetic member (12) may be made using these constituents. The hermetic member (12) may be used to seal an assembly such as a high pressure sodium lamp (10).
