Calcium reacts with cold water rapidly at first, but the reaction is then retarded because of the formation of a film of Ca(OH)2. Calcium reacts vigorously with hot water and with acids, giving off H2 (this does not occur with concentrated HNO3). Calcium reacts with flourine at lower ...
Calcium ions react with carbonate ions present in water to form layers of CaCO3 deposit on heat transfer surfaces. This decreases the efficiency of heat exchangers to transfer heat because of the insulating effect of the deposits (Bansal et al., 2003; Bott, 1995; Helalizadeh et al., 2000;...

· 2H2O), which is a white porous and hygroscopic solid. Continue to heat to produce a hydrate. When the temperature is higher than 200 ℃, the water is completely lost and anhydrous calcium chloride with strong hygroscopicity is formed. Calcium chloride reacts with ammonia to form ammonia ...

Also, the water vapor present in the gaseous phase above the liquid slag reacts with the basic slags and transfers hydrogen in the form of hydroxyl ion. {HEO} + (02-) ~ 2(OH-) [11 The slag, in turn, transfers hydrogen to the refined liquid metal pool until the equilibrium ratio of...
