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...
متن کاملExperimental Establishment of the CaAl2O4–MgO and CaAl4O7–MgO Isoplethal Sections within the Al2O3–MgO–CaO Ternary System
The isoplethal sections CaAl2O4–MgO and CaAl4O7–MgO of the Al2O3–MgO–CaO ternary system have been experimentally established at 1 bar total pressure and air of normal humidity. The sections obtained provide new data and information that are in disagreement with thermodynamic evaluations and optimizations of the Al2O3–MgO–CaO ternary system published to date. These differences arise mainly from ...
متن کاملThermodynamic 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 ...
متن کاملA Novel MgO-CaO-SiO2 System for Fabricating Bone Scaffolds with Improved Overall Performance
Although forsterite (Mg₂SiO₄) possesses good biocompatibility and suitable mechanical properties, the insufficient bioactivity and degradability hinders its further application. In this study, a novel MgO-CaO-SiO₂ system was developed by adding wollastonite (CaSiO₃) into Mg₂SiO₄ to fabricate bone scaffolds via selective laser sintering (SLS). The apatite-forming ability and degradability of the...
