ceramic

· JVASP-41441· HoHg3

HoHg3 is an intermetallic ceramic compound containing holmium and mercury, representing a rare-earth mercury-based phase system. This material belongs to the family of intermetallic ceramics and is primarily encountered in materials research rather than established industrial production. The compound's potential relevance lies in fundamental studies of rare-earth metallurgy, phase diagram exploration, and possible specialized applications where mercury-based intermetallics offer unique electronic or magnetic properties; however, mercury toxicity and volatility constraints severely limit practical deployment compared to conventional alternatives.
