Calcium oxide commonly known as quicklime, is an extensively utilized chemical compound across various industries. It exists as a white, highly caustic, alkaline, and crystalline solid at room temperature, exhibiting distinct physical characteristics that make it indispensable in numerous applications. The typical appearance of quick lime is a pristine white powder, which, when contaminated with impurities, can turn a light yellow or gray hue. One notable physical property of this compound is its hygroscopicity, meaning it has the ability to absorb moisture from the surrounding environment. This characteristic is particularly significant in industries where moisture control is crucial.
Basic Information
Chemical Formula: CaO
Molecular Weight: 56.08
Physical and Chemical Properties
Physical Properties: It appears as white or grayish lumps or granules, odorless, and hygroscopic. It has a melting point of 2572℃, a boiling point of 2850℃, and a density of 3.35g/cm³.
Chemical Properties: Calcium oxide is a basic oxide with the general properties of basic oxides. It reacts with water to form calcium hydroxide, releasing a large amount of heat. It reacts with acids to form corresponding calcium salts and water. It also reacts with some acidic oxides, such as reacting with carbon dioxide to form calcium carbonate.
Application Fields
Construction Industry: It is an important raw material for producing building materials such as cement, lime mortar, and three - mixture soil. The calcium hydroxide formed by its reaction with water can absorb carbon dioxide in the air and gradually harden, making the building structure more solid.
Chemical Industry: It is used to manufacture chemical products such as calcium carbide, bleaching powder, calcium chloride, and calcium hydroxide. It is also an important reagent in many chemical reactions and can be used as a basic catalyst or participate in neutralization reactions.
Metallurgical Industry: As a flux, it can reduce the melting point of ores, promote the removal of impurities in ores, and improve the purity and quality of metals.
Environmental Protection Field: It is used in wastewater treatment to adjust the pH value of wastewater to make acidic wastewater meet the discharge standards. It can also react with heavy metal ions in wastewater to form hydroxide precipitates, thereby removing heavy metal ions. In flue - gas desulfurization, it can react with sulfur dioxide to reduce sulfur dioxide emissions and protect the environment.
Agricultural Field: It can be used to improve acidic soil, increase the pH value of the soil, improve the soil structure, and create good soil conditions for crop growth. At the same time, it can also provide calcium elements for plants, which is helpful for the formation and stability of plant cell walls.
