Mg-Ca-OA complete thermodynamic description of the Mg-Ca-O system and phase diagrams is developed. It is based on our extensive thermodynamic analysis of solid CaO and MgO data and validation of the low-tempera

Phase equil. diagrams for these systems were detd. They show the existence of 7 new compounds: CoTl4(PO3)6, MgTl4(PO3)6, CaTl4(PO3)6, CoTl(PO3)3, MgTl(PO3)3, CaTl(PO3)3, and MgTl2(PO3)4. CoTl4(PO3)6, MgTl4(PO3)6, and CaTl4(PO3)6 are hexagonal and isomorph...
Nine diffusion couples and 32 key samples were prepared to map the phase diagram of the Ca–Mg–Zn system. Phase relations and solubility limits were determined for binary and ternary compounds using scanning electron microscopy, electron probe microanalysis and x-ray diffraction (XRD). The crystal...
In the Mg–Ca binary phase diagram [6], the solubility of Ca in Mg is 0.82 at.% at 516 °C. As the solubility decreases at lower temperature, the precipitation of Mg2Ca phase occurs by aging after a solution-heat treatment. The Mg2Ca has a high melting point of 715 °C and Ca is...
Phase diagram of YCl3-SrCl2 binary system has been measured by means of DTA method, and a new phase in this system was observed by X-ray diffraction. The phase diagrams and thermodynamic properties of the YCl3-AECl2(AE=Mg, Ca, Sr, Ba) systems have been a
The corresponding parameters, especially the tempera- ture, has to be chosen based on the Mg-Al-Ca phase diagram.[25,29] On the one hand, the temperature should be as high as possible to facilitate recrystallization and diffusion processes, as well as dissolving any (here unwanted) ...
The phase diagram was determined in the complete composition range. Large ternary solubilities were found for the binary phases CaMg{sub 2}, Al{sub 2}Ca and Al{sub 3}Ca{sub 8}. Microstructures of samples with compositions near the ternary monovariant eutectic L {yields} CaMg{sub 2} + ...
The phase diagram of Ca-Co pyroxenes is similar to that of Ca-Fe and Ca-Mg ones, with a wide asymmetric miscibility gap, and higher solubility in the Ca-rich side of the gap. The solubility on the Ca-rich side of the gap is related to the radius of the cation substituting. The ...
Despite its importance mentioned above, the phase diagram of the ternary MgeSneCa system has not been established yet. Even isolated equilibrium phase boundary data could not be found in the literature. The aim of this work is to clarify the phase equilibria of this important ternary system over...
