Product Details

Calcium Oxide

Quicklime, more formally known as Calcium Oxide (CaO), is a caustic alkaline substance that is produced by heating limestone in specially designed kilns. There are a wide range of uses for this substance, ranging from mortar to flux, and it has been used by humans for centuries.

Calcium Oxide is manufactured by calcinations of calcium carbonate at high temperature in kiln. Pulverization process is being carried out after calcinations to obtain desired mesh size powder.

Our laboratory is well equipped with latest instruments for evaluation of product. We perform physical and chemical testing of our product as per IS-1514.

Light weight block (AAC)
Quick lime is widely used to manufacture light weight block. It reacts with aluminum and formation of hydrogen takes place which increase the volume of mass.

Petroleum industries

Water detection pastes contain a mix of calcium oxide and phenolphthalein. This paste come into contact with water in a fuel storage tank, the CaO reacts with the water to form calcium hydroxide. Calcium hydroxide has a high enough pH to turn the phenolphthalein a vivid purplish-pink color, thus indicating the presence of water.

Paper industries
Quick lime is used to regenerate sodium hydroxide from sodium carbonate in chemical recovery of Kraft pulp industries.

We supply quick lime product as per customer requirement. Normally supply is available either bulker or
jumbo bag packing.
