Calcium Metal - an overview | ScienceDirect Topics
The production process of calcium metal by the metallothermic reduction process (see Equation 2.9.43) is shown in Figure 2.9.43. The raw material CaCO 3 is calcined to produce CaO. Low magnesia content (MgO) is preferred for the reduction feed materials because magnesia is preferentially reduced in this process, thus lowering the reaction efficiency for calcium metal.
How to Stop Concrete Calcium Deposits | eHow
2 · Calcium deposits--also known as efflorescence—appear as a white substance on the surface of concrete. Efflorescence is the result of soluble salts being wicked to the surface of the concrete by moisture. When the moisture evaporates, the dried salts remain as a
