Hydrated Lime

CaO + H2O → Ca(OH)2 + heat

Chemical name : Calcium Hydroxide

Chemical formula : Ca(OH)2

Hydrated lime, traditionally called slaked lime is the value added downstream product of quicklime which mainly use for water treatment, agriculture plantation and poultry. It is a colorless crystal or white powder and is obtained when calcium oxide (called lime or quicklime) is mixed, or slaked with water. It has many names including hydrated lime, caustic lime, builders’ lime, slack lime, cal, or pickling lime. Calcium hydroxide is used in many applications, including food preparation. Limewater is the common name for a saturated solution of calcium hydroxide. Hydrated lime is preferable in certain industries as it is more safe and stable in normal condition. It is a dry powder produced by reacting quicklime with a sufficient amount of water to satisfy the quicklime’s natural affinity for moisture. The process converts CaO to Ca(OH)2. The amount of water required depends on both the subtle characteristics of the quicklime and the type of hydrating equipment available.
