· JVASP-9384· HoNbO4

HoNbO4 is a holmium niobate ceramic compound belonging to the rare-earth metal oxide family, characterized by a dense crystalline structure. While primarily investigated in materials research rather than established commercial production, this compound is of interest in high-temperature applications and advanced ceramic systems where rare-earth oxides provide thermal stability and unique functional properties. Its potential relevance lies in specialized thermal management, refractory systems, and functional ceramic applications where the combination of holmium and niobium oxides may offer improved performance compared to conventional alternatives.
