Find Verified Calcium Oxide Suppliers, Manufacturers and Wholesalers

Calcium oxide, commonly known as quicklime, is a white, caustic, and crystalline solid with the chemical formula CaO. It is produced by heating calcium carbonate (usually limestone) to high temperatures, causing the release of carbon dioxide. Calcium oxide is highly reactive with water, leading to the production of calcium hydroxide and the release of a significant amount of heat, a process known as slaking. This property makes it valuable in a range of applications, including as a key ingredient in cement production, in agriculture to amend soil pH, and in various industrial processes like metallurgy and the production of chemicals. Its reactivity and versatility in multiple industries underscore its importance as a fundamental chemical compound.

Widely used in pesticides, papermaking, food, petrochemicals, leather making, chemicalbook purification of wastewater, etc. It can also be used for drying ammonia in laboratories and dehydrating alcohols. Uses Used as a drug carrier. Uses Analytical reagents, calcium oxide is used in steel, pesticides, medicines, non-ferrous metals, fertilizers, leather making, calcium hydroxide, drying ammonia in laboratories, carbon dioxide absorbent, dehydration of alcohols, etc. Uses Calcium oxide is used to make calcium carbide, soda ash, bleaching powder, etc., and is used as a building material, refractory material, desiccant, soil conditioner and calcium fertilizer.
Calcium oxide is also an inorganic dehydrating agent. It reacts with water to produce calcium hydroxide and can also absorb carbon dioxide. Calcium oxide powder can be added to some special sealants, water-curing adhesives and other systems. Calcium oxide can be used as an analytical reagent, a carbon dioxide absorbent in gas analysis, a spectral analysis reagent, and a high-purity reagent for epitaxy and diffusion processes in semiconductor production, laboratory ammonia drying and alcohol dehydration, etc. Application Quicklime is generally calcined from limestone. Quicklime has long been used to make desiccants due to its excellent water absorption properties. The main component of quicklime desiccant is calcium oxide. The drying principle is that calcium oxide absorbs water to generate calcium hydroxide. It is widely used in various industries such as food and clothing due to its low cost and high cost performance.
