· JVASP-30481· HoH2ClO2

HoH₂ClO₂ is a rare-earth oxide chloride ceramic compound containing holmium, a lanthanide element. This is a research-phase material rather than an established commercial ceramic; it belongs to the family of rare-earth oxyhalides being investigated for advanced functional and structural applications. The holmium-based chemistry suggests potential interest in optical, magnetic, or thermal applications where rare-earth dopants or host materials provide unique electronic or photonic properties.
