· JVASP-88736· CaMgSi2O6

CaMgSi₂O₆ is a calcium magnesium silicate ceramic belonging to the pyroxene mineral family, characterized by a chain silicate crystal structure. This compound is encountered in refractory applications, glass-ceramic systems, and geological/materials research contexts where high-temperature stability and chemical inertness are required. Its notable attributes include thermal stability at elevated temperatures and compatibility with silicate-based systems, making it relevant for engineers working with high-temperature composites, industrial refractories, or bioactive ceramic formulations.
