MgFeSiO4
MgFeSiO4 is a thermodynamically stable, insulating complex oxide that serves as a specialized member of the spinel and hexagonal ferrite family.
About MgFeSiO4
MgFeSiO4 is a complex oxide that functions as a wide-band-gap insulator. Its status as a thermodynamically stable phase on the convex hull makes it a significant subject for research within the broader category of spinel and hexagonal ferrites. The material is characterized by a robust atomic arrangement that supports its stability under various conditions.
This compound is primarily studied for its structural properties and potential roles in advanced materials science. As a member of the ferrite-related family, it provides a unique platform for understanding how the integration of silicon into a ferrite-like framework influences electronic behavior and overall lattice stability.
Key Properties
Cross-validated computational properties for MgFeSiO4, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.

How It Compares
Within the spinel and hexagonal ferrites class.
Within the diverse group of spinel and hexagonal ferrites, MgFeSiO4 distinguishes itself through its specific stoichiometry, which contrasts with the more traditional spinel structures like MgFe2O4. While MgFe2O4 is a well-known magnetic material, MgFeSiO4 occupies a unique niche, offering a different balance of stability and electronic characteristics that sets it apart from the purely iron-based or zinc-substituted members of the class.
