· JVASP-19080· Cd2GeO4

Cadmium germanate (Cd₂GeO₄) is an inorganic ceramic compound belonging to the ternary oxide family, combining cadmium and germanium oxides into a crystalline structure. This material is primarily of research and specialized industrial interest, investigated for applications in optoelectronics, scintillation detection, and solid-state physics where its specific crystal structure and electronic properties offer potential advantages. While not a commodity ceramic, Cd₂GeO₄ represents an important member of the germanate family and is studied for photoluminescent and radiation-detection applications where alternatives like bismuth germanate or other heavy-element oxides may not provide the desired performance characteristics.
