Calcium Hydroxide

Calcium hydroxide is a white-colored compound with the chemical formula Ca(OH)₂, characterized by a crystalline structure. It is commonly obtained through the calcination of limestone (calcium carbonate). It exists in ion form in aqueous solution and is often referred to as "slaked lime." It is a chemical compound widely used in industrial applications.

Construction Sector: Calcium hydroxide is extensively used in the production of construction materials. It is used in concrete production to accelerate the hydration process and enhance stability. Additionally, it is an effective material used in soil improvement and soil stabilization.

Water Treatment: Calcium hydroxide is employed in pH adjustment processes in water treatment facilities. By increasing the alkalinity level of water, it aids in the precipitation of various pollutants.

Paper Industry: It serves as a substance used in paper bleaching processes. Calcium hydroxide reacts with the chemicals used to bleach cellulose pulp.

Environmental Applications: Calcium hydroxide is also present in pollution control systems used to reduce air pollution. It is effective in neutralizing gases such as sulfur dioxide.

Chemical Industry: It can be used as a catalyst in various chemical reactions. Additionally, due to its basic properties, it can be used as a reactive agent in different chemical syntheses.

While calcium hydroxide generally has low toxicity, dust forms can cause skin and eye irritation. Therefore, the use of appropriate protective equipment (gloves, protective eyewear, mask) is recommended during handling. Furthermore, ensuring proper storage conditions is essential.
