Calcium oxide (CaO), a.k.a. burnt lime, quicklime, pebble lime, and calcia, is an odorless gray or white-gray chemical compound primarily used in manufacturing applications. Calcium oxide is typically produced via thermal decomposition of limestone or other materials containing calcium carbonate. While China is the world’s leading calcium oxide producer, the United States is also a major player in the calcium oxide marketplace.
If you’re looking for a calcium oxide distributor you can trust, look no further than Brenntag, N.A. As one of the world’s leading providers of high-quality chemicals and ingredients to companies in a wide range of industries, we’re known for exceeding the expectations of our customers.
Calcium Oxide uses and applications
The ability of CaO to react with silicates and other materials to form solutions makes it amenable to numerous industrial processes. Manufacturers in the steel and metallurgic industries are leading consumers of calcium oxide, as they use it for the melting and purification of other metals. CaO neutralizes the acidic oxides forming on the surface of the metal, which produces a molten slag.
This process is essential for refining the finished steel products and preparing it for additional manufacturing steps.
Calcium oxide is also an essential ingredient in the production of cement. When converted to calcium hydroxide, CaO can be used in the manufacturing of products such as soft drinks, infant formulas, hair products, and leather goods. The petroleum industry makes use of CaO to produce a paste that can indicate the presence of water in fuel storage tanks.
Gardening and farming applications for CaO include the manufacturing of fertilizers used in the treatment of acidic soil. Other common applications include wastewater treatment, as a water softener and as an ingredient in the porcelain and glass manufacturing processes.
Calcium Oxide Properties and Characteristics
Calcium oxide is soluble in water and glycerol. It features a molar mass of 56.0774 g/mol, a melting point of 4,662° F (2,572° C) and a boiling point of 5,162° F (2,850° C). Although calcium oxide is a non-flammable material, it does require the implementation of certain safety precautions when handled, stored or used in manufacturing. It reacts vigorously with water, which can lead to irritation when inhaled or when coming in contact with skin or eyes. In extreme cases, calcium oxide exposure can cause abdominal pain, nausea, vomiting and severe burns.
