The law of conservation of mass states that matter cannot be created or destroyed, which means there must be the same number atoms at the end of a chemical reaction as at the beginning. To be balanced, every element in CaCl2 + Na2HPO4 + NaOH = Ca5(PO4)...
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...
