· JVASP-41464· Tm2CoOs

Tm₂CoOs is a ternary intermetallic compound combining thulium (a rare-earth element), cobalt, and osmium. This is a research-phase material primarily investigated for its potential as a corrosion-resistant, high-density structural or functional material, particularly within the families of rare-earth transition metal compounds known for exceptional hardness and thermal stability. The combination of a dense rare-earth metal with refractory cobalt and osmium suggests applications in extreme-environment aerospace or nuclear contexts, though industrial deployment remains limited and the material is primarily studied for fundamental materials science understanding and potential niche high-performance applications.
