High surface area calcium hydroxide refers to a form of calcium hydroxide that has been specially processed or treated to have a significantly larger surface area compared to its conventional counterpart. This increased surface area is achieved by modifying the particle size, shape, or by introducing structural or textural features that enhance the available surface for chemical reactions or adsorption.
High surface area calcium hydroxide is often produced through techniques such as milling, grinding, or precipitating with specific additives. These methods aim to break down larger particles into smaller ones or create a porous or structured morphology, which leads to a greater surface area per unit mass.
The exact surface area of high surface area calcium hydroxide can vary depending on the specific manufacturing process and parameters used. However, it is generally reported to have surface areas ranging from 50 to several hundred square meters per gram (m²/g) or even higher.
The increased surface area of high surface area calcium hydroxide makes it more reactive and suitable for various applications. It can be utilized in areas such as environmental remediation, wastewater treatment, catalysis, gas adsorption, and as a component in advanced materials or composites.
Some of the common applications of high surface area calcium hydroxide include:
Environmental Remediation
Calcium hydroxide is used in environmental remediation processes, such as treating acidic wastewater and neutralizing acidic soils. Its high surface area allows for efficient neutralization of acidic contaminants, helping to restore pH balance and improve environmental conditions.
Water Treatment
Calcium hydroxide is employed in water treatment processes, particularly for pH adjustment and chemical precipitation. Its high surface area facilitates effective mixing and reaction with acidic or corrosive components, aiding in the removal of impurities and the treatment of drinking water, industrial
