· JVASP-18412· TaH2

Tantalum hydride (TaH₂) is a ceramic compound combining tantalum metal with hydrogen, belonging to the interstitial hydride family of materials. This material is primarily of research and specialized industrial interest, valued for applications requiring high-density refractory properties and studied for hydrogen storage, catalytic, and advanced metallurgical applications. TaH₂ represents a niche material where the addition of hydrogen to tantalum modifies mechanical and thermal characteristics compared to pure tantalum, making it relevant for extreme-environment or hydrogen-related engineering contexts.
