HYDRATED LIME

Hydrated lime  is  a stable, dry, fine powder produced  by  the chemical  combination of quicklime with water.  This is the  most concentrated form of lime.

Hydrated  lime, apart from building industries, is  also  largely used  in chemical industries as a cheapest alkali available.   It is consumed in hundreds of solidliquid phase reactions.  Hydrated lime  requirements  definitely exceed the vast tonnage  of  quick lime  required  in  dry, thermal  processes  such  as  sintering, smelting,   and   fluxing  etc.   Hydrated  lime  is   used   for neutralization,    coagulation,    canticization,    dehydration, hydrolyzation  and  absrption.   It is also used  as  a  flux  in metallurgy,  as a specified lubricant, as a bonding agent,  as  a filler,  as  a  raw  material and  also  in  the  manufacture  of refrectories.  The present existing manufacturing capacity in the country for the manufacture of hydrated lime is not sufficient to meet  the  growing  demand of its dependent  chemical  and  other industries as also in building industry.  Raw materials,  process equipments, and the necessary know-how involved in the manufacture of hydrated lime are available indigenously.

The  term  lime has broad connotation and frequently is  used  in refering to limestone.  According to precise definition lime  can only be a burned form:

Quick lime and hydrated lime.

These products are oxides or hydroxides of calcium and magnesium, expect hydraulic types in which the CaO & MgO are chemically combined with impurities. The oxide is converted to a hydroxide by slaking on exothermic reaction in which  the  water combines chemically with the lime.
