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 کاملTheoretical Studies of the g Factors for Co2+ in MgO and CaO Crystals
This paper presents a cluster approach to the calculation of the g factors for 3d7 ions in cubic oc tahedral crystals, in which the parameters related to the configuration interaction and the covalency reduction effects are obtained from optical spectra of the studied crystals, and so no adjustable parameters are applied. From the approach, the g factors for MgO:Co2+ and CaO:Co2+ are cal cula...
متن کاملThe growth and characterization of layered, binary thin-film oxides: MgO–NiO and CaO–NiO
Layered, binary thin-film oxides of NiO, MgO and CaO have been prepared and characterized using low energy electron diffraction, Auger electron spectroscopy, energy loss spectroscopy, ion scattering spectroscopy, and temperature programmed desorption using probe molecules. Epitaxial growth was observed for the NiO–MgO and CaO–NiO systems; however, superior wetting was found for NiO–MgO relative...
