· JVASP-46072· HoSO

HoSO is a ceramic compound based on holmium and sulfur oxides, belonging to the rare-earth ceramic family. While not widely documented in conventional engineering databases, materials in this class are primarily explored in research contexts for specialized optical, magnetic, and electronic applications where rare-earth elements provide unique functional properties. Engineers would consider such compounds for high-temperature stability, luminescence, or magnetic functionality in niche applications where standard ceramics are insufficient.
