Physical and chemical properties Calcium hydroxide (calcium hydroxide), an inorganic compound, chemical formula Ca(OH)2, commonly known as slaked lime or hydrated lime. It is a white powdery solid. After adding water, it presents two layers, the upper aqueous solution is called clear lime water, and the lower suspension is called lime milk Chemicalbook or lime slurry. The upper clear liquid clear lime water can be used to test carbon dioxide, and the lower turbid liquid lime milk is a building material. The solubility of calcium hydroxide decreases with increasing temperature. It is insoluble in alcohol, soluble in ammonium salts and glycerol, and can react with acid to generate corresponding calcium salts. At 580â??, it decomposes into calcium oxide and water
Calcium hydroxide is a strong base with bactericidal and antiseptic capabilities, and has a corrosive effect on skin and fabrics. However, due to its low solubility, the degree of harm is not as great as strong bases such as sodium hydroxide. Calcium hydroxide is widely used in industry. It is a commonly used building material, and is also used as a bactericide and chemical raw material.
White powder with fine chemical properties. Used in the manufacture of bleaching powder, water softener, water disinfection clarifier, and construction industry. Used in pharmaceuticals. Can be used as an additive in rubber and petroleum industries. Used in lubricating oil to prevent coking, sludge deposition, neutralization and corrosion. Can also be used as a water softener, disinfectant, antacid, etc. Used as an analytical reagent, carbon dioxide absorbent, and also used in organic synthesis. Used in the manufacture of bleaching powder, water softener, depilatory, disinfectant, antacid, astringent and various calcium salts. Used in the inspection of carbon dioxide, gas absorption. Leather depilation, insecticide, water treatment.
Calcium hydroxide is used in industrial settings, such as a flocculant and to raise the pH of the water , it is also used as an intermediate in paper production and in the manufacturing of cements, mortars and plasters. It is also used as an accelerant in processes for the production of synthetic rubber and plastics. Calcium Hydroxide is also used in the manufacture of paints and waterproof coatings and as an additive to lubricants and oil drilling fluids, to improve the viscosity of the fluids.
