· JVASP-10866· Ho2HgO4

Ho₂HgO₄ is a rare-earth mercury oxide ceramic compound combining holmium (a lanthanide) with mercury in an oxidized matrix. This material is primarily of research interest rather than established industrial use, belonging to the family of complex metal oxides studied for their potential electronic, magnetic, or catalytic properties. While not yet widely deployed in commercial applications, such rare-earth mercury oxides are investigated for specialized ceramic functions where unique phase chemistry or high-density characteristics may offer advantages over conventional materials.
