For CaO/SiO 2 =0.30 and 0.34, n values obtained experimentally are 1.9 and 2.3, respectively, suggesting that the dimensionality of growth must be a mix of both two- and three-dimensional growths. For CaO/SiO 2 =0.38 and 0.42, the n values are about 3.5, indicating that the crystallization presumably occurs by three-dimensional crystallization ...

Thermodynamics of Reactions Among Al2O3, CaO, SiO2 …

4. Summary. 1) When Al 2 O 3 and Fe 2 O 3 simultaneously react with CaO, calcium silicates are firstly formed, and then calcium ferrites. In thermodynamics, when one mole Al 2 O 3 reacts with CaO, the sequence of generating calcium aluminates are 12CaO 7Al 2 O 3, 3CaO Al 2 O 3, CaO Al 2 O 3, CaO 2Al 2 O 3.

The CaO–Al2O3–SiO2 system has been assessed with the CALPHAD technique, based on recent assessments of its binary systems. A new species AlO2−1 was introduced for modeling liquid Al2O3.

Equilibrium Phase Relations of the CaO-SiO2-Ti3O5 …

The phase relations of TiOx containing systems in reducing atmospheres are extremely important for understanding the smelting process for vanadium titano-magnetite. In the present work, the equilibrium phase relations for the core CaO-SiO2-Ti3O5 system at 1400 °C and oxygen partial pressure of 10−16 atm were determined. Ti3O5 was confirmed as the …
