· JVASP-42115· PmCdHg2

PmCdHg2 is a ternary ceramic compound combining promethium, cadmium, and mercury. This is a specialized research material rather than a commercial engineering ceramic, and belongs to the family of intermetallic and mixed-valence compounds explored for their unique electronic and structural properties. As a promethium-containing phase, this material exists primarily in laboratory and nuclear research contexts, where it may be investigated for its potential in high-density applications, radiation shielding studies, or fundamental materials science research into rare-earth and heavy-metal ceramic phases.
