Phase Equilibria Studies in the CaO-MgO-Al2O3-SiO2 System with Al2O3/SiO2 Weight Ratio of 0.4

Crystal chemistry of a Mg-vesuvianite and implications of phase equilibria in the system CaO-MgO-Al2O3-SiO2-H2O-CO21

Chemical analysis (including H,, F,, FeO, Fe,O,) of a Mg-vesuvianite from Georgetown, Calif., USA, yields a formula, R . 9 ? M g l . B B F e ~ . ~ 0 A ' 1 0 . ~ 7 S i 1 ~ . 8 1 06,.,,(OH)8.*4~0.,4~ in good agreement on a cation basis with the analysis reported by Pabst (1936). X-ray and electron diffraction reveal sharp reflections violating the space group P4/nnc as consistent with domains hav...

Ternary System Al2O3–MgO–CaO: I, Primary Phase Field of Crystallization of Spinel in the Subsystem MgAl2O4–CaAl4O7–CaO–MgO

Using a novel experimental procedure in the field of ceramics/materials science that is based on the precise microanalysis (scanning electron microscopy, coupled with wavelength-dispersive spectroscopy) of the phases that are present in equilibrated specimens, the solid-state compatibility relations in the subsystem MgAl2O4–CaAl4O7–CaO– MgO and the melting relationships in the subsystems MgAl2O...

Thermodynamic simulation on mineralogical composition of CaO–SiO2–Al2O3–MgO quaternary slag system

It is necessary to elucidate the crystallization thermodynamic of mineralogical phases during the cooling process of the molten BFS with different chemical composition, because the high-melting point mineral phase maybe crystallized during the fiber forming and thereafter cooling process. Thermodynamic calculation software FactSage6.4 and the hot remelting experiments were performed to explore ...

Kinetics of spinel formation and growth during dissolution of MgO in CaO-Al2O3-SiO2 slag
