Quicklime is commonly referred to as calcium oxide (CaO). Burnt lime is a common chemical compound. Quicklime is white and solid at room temperature, and is usually inexpensive to purchase. China is the leading producer of Quicklime and produces more than eight times as much as the United States.

Quicklime is most commonly used in the basic oxygen steelmaking process and also in the making of aerated concrete blocks. Quicklime can be very dangerous if it is inhaled or comes in contact with wet skin or eyes due to the fact that Quicklime reacts violently with water. While Quicklime is not considered flammable, mixing it with water can release enough heat to ignite materials if they’re nearby.
