About Calcium Oxide Powder, Lab Grade

Calcium oxide (CaO), also known as burnt lime, is a widely used chemical compound. At room temperature, it is a white, caustic, alkaline, and crystalline solid. The term "lime" refers to calcium-containing inorganic products that are mostly composed of carbonates, oxides, and hydroxides of calcium, silicon, magnesium, aluminum, and iron. Quicklime, on the other hand, refers to the single chemical component i.e., calcium oxide. The Lab Grade Calcium Oxide at Lab Alley is mostly suitable for educational and research purposes.
