Calcium Oxide (Quick Lime) Manufacturers and Suppliers in India
Sudarshan Group supplies Calcium Oxide, commonly called Quick Lime, in powder form to industrial buyers across India and export markets. Quick Lime is used in steel making, water treatment, construction, paper manufacturing and chemical processing, where it works as a flux, a neutralising agent and a source of reactive calcium. Our production is backed by in-house grinding and classification, with a certificate of analysis released for every consignment.
What Is Calcium Oxide?
Calcium Oxide has the chemical formula CaO and is made by heating limestone (CaCO3) at high temperature in a process called calcination, which drives off carbon dioxide and leaves a white, highly reactive solid. It is then ground into powder of a controlled fineness. When mixed with water, Quick Lime reacts quickly and gives off heat to form calcium hydroxide, also known as slaked lime, which is the property that makes it useful across so many industries.
Applications by Industry
Steel and Metallurgy
Quick Lime is used as a flux in steel making, where it combines with silica, phosphorus and sulphur to form slag that can be removed from the molten metal. It is also used in the production of other non ferrous metals such as aluminium, copper and magnesium.
Water and Wastewater Treatment
Quick Lime raises the pH of water, softens hard water and helps precipitate heavy metals and suspended solids. Treatment plants use it to neutralise acidic effluent before discharge.
Construction and Building Materials
Quick Lime is the base material for lime mortar, plaster and soil stabilisation. It is also used in the manufacture of autoclaved aerated concrete blocks and calcium silicate bricks.
Paper and Pulp
In the paper industry, Quick Lime is used in the causticising step of the kraft process to recover sodium hydroxide, and as a source of calcium for making precipitated calcium carbonate.
Chemical and Sugar Processing
Quick Lime is used to make calcium carbide, calcium hypochlorite and other calcium compounds. In sugar refining, it is used to purify cane juice by removing impurities before crystallisation.
Agriculture and Soil Treatment
Farmers and soil specialists use Quick Lime to raise the pH of acidic soil and improve nutrient availability for crops.
