Calcium Hydroxide

Available Packing Sizes: 

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.

Product Application: 

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.


Product Dose: 

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.

Products based on calcium hydroxide have a surprisingly wide variety of applications. The fact is that slaked lime has been used since time immemorial and with amazing results. Some of imprtant application as below -

  • Waste Water/Water Treatment
  • Construction
  • Flue Gas Treatment
  • Chemical Processes and Chemical Reactions
  • Petrochemicals
  • Calcium Salts (citrates, phosphates, stearates),
  • Acid Neutralization
  • Chemical Reactions
  • Calcium Enrichment (food, pharmaceutical, neutraceutical).


Calcium hydroxide can be found in the food industry providing calcium and as a pH modifier, as well as in the management of gases, as it has a high effectivity in the capture of acidic pollutants from industrial smoke and vapours. It is also an additive in feeds improving animal nutrition, and is used in animal-pens for its disinfecting power, lowering the number of pathogens and virus. In the sugar-industry it can be used to precipitate out impurities and to obtain purified sucrose.

It also brings benefits in sludge treatment as it is an exceptional aid in the elimination of micro-organisms and bacteria which at the same time neutralizes bad smells.Its properties are especially useful for water treatment, because it acts as a clarifier, a coagulant, a neutralizer and for the precipitation of dissolved pollutants.


Handling  :  

Use in a well-ventilated area. Wear protective gloves/clothing and eye/face protection. Do not ingest. Do not breathe dust or fume. Avoid contact with skin, eyes and clothing. Keep away from extreme heat and flame. Keep away from bases, metals and other incompatibles. Keep container tightly closed when not in use. Keep only in original container. Wash thoroughly after handling. During preparation or dilution, always add liquid slowly to water and with constant stirring.

Storage : 

Conditions for safe storage : Store in a cool, dry, well-ventilated area. Store locked up. Store away from incompatibles and out of direct sunlight. Storage area should be clearly identified, clear of obstruction and accessible only to trained and authorized personnel. Inspect periodically for damage or leaks. Store in corrosion-resistant containers. Keep only in original container.
