Calcium carbonate (CaCO3) was synthesized in the CaCl2-Na2CO3-H2O reaction system at the reaction temperature of 40, 50, 60, and 70℃. The initial pH was changed to 2.4-11.0 at 50-70℃. The initial pH was adjusted by changing the pH of CaCl2 aqueous solution using HCl and NH3 aqueous...

摘要: 本文用差热分析、热重分析和X射线衍射等方法,研完了 CaCl2对CaCO3—SiO2混合物中 CaCO3分解速度的影响以及各不同温度下煅烧的反应产物。结果表明,在 CaCO3—SiO2配料中加入 CaCl2,能够成倍地加速 CaCO3的分解速度,并使 C2S 的生成温度显著提前。 展开 ...
The route by CaCl2 and Na2CO3 exhibits some advantages, but the consumption of Na2CO3 is a deficiency. Therefore, this work studies the precipitation of CaCO3 with CaCl2 in NH3-CO2 aqueous solution, which will make the overall reaction "CaCO3 -> CaCO3" if tracing the origin of the react...
Vaterite, the least stable phase among three anhydrous polymorphs of calcium carbonate (CaCO3), was prepared via the reaction between the ethanol solution of calcium chloride (CaCl2) and the aqueous solution of sodium carbonate (Na2CO3), which is named ethanol-calcium method. The effects of aging...
These two steps consist of a first stage with precipitation of Ca(OH)2, Mg(OH)2, and Mn(OH)2 by NaOH and a second stage with Li2CO3 recovery by neutralization using HCl, carbonation using Na2CO3, and concentration using evaporation. Chemical modeling with OLI-Systems® software was used ...
