CAS 1305-78-8

Calcium oxide

Description:

Calcium oxide, commonly known as quicklime, is an inorganic compound with the chemical formula CaO and a CAS number of 1305-78-8. It is a white, caustic solid that is produced by the thermal decomposition of calcium carbonate (limestone) in a process known as calcination. Calcium oxide is highly reactive, particularly with water, forming calcium hydroxide, or slaked lime, which is an exothermic reaction. This compound is characterized by its high melting point and strong basicity, making it an effective alkaline agent. It is widely used in various industrial applications, including steelmaking, construction, and environmental processes such as water treatment and soil stabilization. Additionally, calcium oxide plays a role in the production of cement and glass. Due to its caustic nature, it can cause irritation to skin and eyes, necessitating appropriate safety measures during handling. Overall, calcium oxide is a versatile compound with significant importance in both industrial and environmental chemistry.

Controlled Product

CAS: 1305-78-8

Calcium oxide is a chemical compound that is used in the process of wastewater treatment. It removes phosphorus from sewage by forming insoluble calcium phosphate and prevents the release of phosphate into natural waterways. Calcium oxide also has been shown to remove chromium, nickel, copper, and zinc from wastewater. The removal of these metals may be due to the oxidation of metal hydroxides which are then precipitated by calcium oxides or through the formation of insoluble metal oxides. Calcium oxide can also be used to remove potassium dichromate from water vapor. Calcium oxide is an oxidizing agent that can react with metals at high temperatures and can be used as a catalyst for many reactions. The activity index for calcium oxide ranges between 1-3 and its surface methodology is Langmuir adsorption isotherm.
