· JVASP-99073· Ge4PbO9

Ge4PbO9 is a lead-germanium oxide ceramic compound belonging to the family of mixed-metal oxides. This material is primarily investigated in research contexts for applications requiring specific optical, electrical, or thermal properties that arise from the combined contribution of germanium and lead oxide phases. Industrial adoption remains limited, with primary interest in specialized glass and ceramic systems where lead-germanium combinations offer advantages in radiation shielding, optical transmission, or high-temperature stability compared to single-component alternatives.
