The paper presents research results of the thermal effect on the structure, phase composition, and morphology of natural magnesite (MgCO3) from the Savinsky deposit (Irkutsk region) used as a raw material. Two types of thermal treatment are applied to test specimens, namely: isothermal exposure at 1173 K and heating and melting in thermal plasma at a bulk temperature of 6500 K. According to the qualitative phase analysis, major phases include MgCO3 and MgO with hexagonal and cubic crystal systems. Complete information is obtained for the lattice structure both in the initial state and after Rietveld refinement of structural parameters. The high-throughput framework Aflow is used to evaluate the phase stability of the crystal lattices using the convex hull construction. The stability plot of MgCO3 and energy color matching are suggested with regard to spin polarization.
