- Product Description
Calcium hydroxide is an inorganic compound with the chemical formula Ca(OH)2 and a molecular weight of 74.10.Commonly known as burnt lime or hydrated lime.It is a white hexagonal powder crystal.Density 2.243g/cm3.At 580¡æ,it loses water and forms CaO.
After adding calcium hydroxide to water,it is divided into two layers.The upper aqueous solution is called clear lime water,and the lower suspension is called lime milk or lime slurry.The upper clear liquid lime water can detect carbon dioxide,while the lower turbid liquid lime milk is a building material.Calcium hydroxide is a strong alkali with antibacterial and anti-corrosion properties,and has a corrosive effect on the skin and fabrics.Calcium hydroxide is used in the production of bleaching powder,hard water softener,disinfectant and insecticide,leather depilatory,sugar refining,and building materials.
