Calcium Oxide is an inorganic compound with the chemical formula CaO and CAS Number 1305-78-8. Commonly known as quicklime, it is typically supplied as a white to off-white solid or powder. It reacts readily with water to produce calcium hydroxide, releasing a considerable amount of heat.

Calcium Oxide is valued for its chemical reactivity and its role as a source of calcium in various chemical processes. Common laboratory applications include inorganic chemistry experiments, preparation of calcium-based compounds, neutralisation studies, and research involving acid-base reactions and mineral materials.

Its properties also make Calcium Oxide useful in chemical preparation, materials research, and selected industrial processes. Due to its reaction with moisture and water, it should be stored under suitable dry conditions to maintain product quality and minimise unwanted reactions.

The appropriate grade and purity should be selected according to the requirements of the intended application.

KSFE Malaysia supplies laboratory chemicals and scientific products for research institutions, educational facilities, and general laboratory applications.

Safety Note: Calcium Oxide is corrosive and reacts with water to release heat, which may cause severe burns or eye damage. Avoid inhalation of dust and contact with the eyes and skin. Use appropriate personal protective equipment and handle the product in a dry, well-ventilated area. Keep the container tightly closed and protect it from moisture. Follow the supplier's safety data sheet (SDS) for proper handling, storage, and disposal.
