Calcium Hydroxide
Calcium Hydroxide pure powder
Application & Uses
Soft, white crystalline powder with an alkaline, slightly bitter taste. Used for mortar, cements, white wash, soil conditioner, drying hold, and cleaning.
Calcium Hydroide has many application including Mortar, plasters, cements, calcium salts, causticizing soda, depilatory, unhairing of hides, whitewash, soil conditioner, ammonia recovery in gas manufacture, disinfectant, water softening, purification of sugar juices, accelerator for low-grade rubber compounds, Shipping , Marine and petrochemicals.
Dosage & Directions for Use
Calcium Hydroxide, is a versatile product with interesting properties that brings great benefits for industry, construction and the environment because it can be applied in several formats.Calcium hydroxide which to some may sound a little outlandish created in a laboratory and to others like something from science fiction, is almost omnipresent in daily life. It is obtained through a process which hydrates calcium oxide, in this reaction the hydration of the lime generates heat, something that favours, in many applications, the drying and disinfecting of the materials that are treated.

Product Description & Chemical Profile
Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula Ca(OH)2. 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 use as a raw material for many chemical processes that require a highly reactive, high purity, consistent product. The small particle size and top size make it an excellent choice for many applications. RXSOL Calcium Hydroxide prepared to customer specifications.
