Hydrated Lime Nanopowder (Ca (OH)2, Purity: 99.9%, APS: <100nm)

Hydrated Lime Nanopowder

Hydrated lime (Ca(OH)₂), also known as calcium hydroxide, is a highly versatile chemical compound that plays an essential role in many industrial, environmental, and chemical processes. When produced at the nanoparticle scale, hydrated lime exhibits enhanced reactivity, surface area, and chemical properties, making it suitable for a variety of advanced applications.

Hydrated lime nanopowder is typically synthesized by wet grinding or precipitation methods to reduce the particle size and increase its surface area. The increased surface area of hydrated lime in nanopowder form leads to improved reactivity compared to bulk hydrated lime, making it more effective in processes such as water treatment, pollution control, and construction. Its alkaline nature and ability to neutralize acids make it useful in a broad range of applications across multiple industries.

Applications

Environmental Applications:

Water Treatment: Hydrated lime nanopowder is widely used in water purification processes due to its ability to neutralize acidity and remove impurities such as heavy metals and suspended solids. In water treatment plants, it is used to treat drinking water, wastewater, and to treat acidic mine drainage by adjusting the pH level and removing contaminants.

Air Pollution Control: Hydrated lime nanoparticles are used to capture acid gases, including sulfur dioxide (SO₂), nitrogen oxides (NOx), and carbon dioxide (CO₂) in the flue gases from power plants and industrial boilers. The increased surface area of the nanopowder enhances its ability to adsorb these gases, contributing to air pollution control.

Soil Remediation: In environmental clean-up projects, hydrated lime nanopowder can be used for soil stabilization and to neutralize acidic soils.
