· JVASP-21353· MgFeSi2O6

MgFeSi2O6 is an iron-magnesium silicate ceramic belonging to the pyroxene mineral family, characterized by a framework silicate structure with divalent metal cations. This compound is primarily of interest in geomaterials science and high-temperature applications, where it naturally occurs as the mineral ferrosilite or in synthetic form for refractory and structural ceramic research. Its notable attributes include chemical stability at elevated temperatures and compatibility with other silicate phases, making it relevant for applications requiring thermal resistance and phase stability in complex mineral assemblages.
