Differential thermal analysis and quenching experiments were used to establish the ternary phase diagram CaO-CaF 2 -2CaO.SiO 2 . Hermetically-closed platinum capsules were used to prevent fluorine loss in the form of HF, SiF 4 , and CaF 2 by reaction of the CaF 2 with water vapor or SiO...
Computation of phase equilibria in the multicomponent CaO–SiO2–MgO–ZrO2–CaF2 slags Due to the absence of information on the phase diagram of the multicomponent CaO–SiO2–MgO–ZrO2–CaF2 slags, a computational estimation was needed. The phase diagram of the CaO–SiO2–ZrO2-7 mass% MgO system...
Since the phase diagram of the CaF2–CaO–Al2O3–SiO2–B2O3 slag has not been reported so far, the complex molecules will be deduced by using subsystems of the five-component slag. According to the hypothesis of the IMCT [47], 22 kinds of complex molecules can be found in the slags...

Diagram of continuous cooling transformation and that of isothermal (time temperature) transformation for the slag have been constructed to characterize the solidification behavior of the slag with cooling rates between 3.125 and 100 K/minutes and temperature between 1373 and 1598 K. Depending on the ...
The primary glass is converted into glass-ceramic by thermally formed nano-crystalline phase dispersed thorough a glass matrix [1], [2]. In new transparent glass-ceramics, the optically active rare earth ions distribute into fluoride crystal phase that results in an economical alternative with ...
Therefore, the isothermal phase diagram of CaO–SiO2–CaF2–Ce2O3 system was constructed, and the phase equlibria data of REEs in REE-bearing slag were provided in this study. On this basis, the phase equilibria of the RE-phase in CaO–SiO2–CaF2–Ce2O3 system was investigated, the ...
However, the shear stress has no effect on the crystalline phase. The influence of different shear stresses on the crystallization ability of molten slags is related to the crystal nucleation and growth mechanisms. The crystalline fraction of the slag films at 300 rpm (69 s−1) is 44.7%, ...
The silica activities of slags in the CaF2CaOSiO2 system (NCaO:NSiO 2>3:2) have been determined at 1450掳C by measuring the equilibrium partial pressure of carbon monoxide for the reaction (SiO2)+3C (s) =SiC (s) +2CO (g) The results have been correlated with phase diagram ...
