Calcium Oxide

We are manufacturing Calcium Oxide in Technical, Pure & LR Grade.
These Products are available in 50 kgs Bag/Drum.

Calcium oxide (CaO), commonly known as quicklime or burnt lime is a widely used chemical compound. It is a white, caustic, alkaline, crystalline solid at room temperature. The broadly used term "lime" connotes calcium-containing inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminum, and iron predominate. By contrast, "quicklime" specifically applies to the single chemical compound calcium oxide.
