Slaked Lime
A Versatile Solution for Industrial and Environmental Applications
Slaked lime, also known as calcium hydroxide (Ca(OH)₂), is a vital industrial chemical used across a wide range of sectors — from construction and water treatment to metallurgy and chemical manufacturing. Produced by hydrating quicklime (calcium oxide) with water, slaked lime is valued for its chemical reactivity, purity, and versatility.
At PARS HASTI ASIA, we manufacture high-quality slaked lime in compliance with international standards, ensuring consistency, safety, and performance in every application.

What is slaked Lime?
slaked lime is a dry, white powder obtained by combining quicklime with water in a controlled process. The result is a highly reactive compound with strong alkaline properties, making it an ideal material for both neutralization and purification processes.
Chemically, the reaction is as follows:
CaO (quicklime) + H₂O → Ca(OH)₂ (slaked lime)
This compound plays a foundational role in industrial chemistry, environmental engineering, and materials science.

Key Applications of slaked Lime
1. Water and Wastewater Treatment
slaked lime is widely used to adjust pH levels, remove heavy metals, and precipitate impurities in drinking water and wastewater treatment plants. Its high alkalinity makes it effective for neutralizing acidic waters and improving water quality.
2. Construction and Civil Engineering
In construction, slaked lime is used in soil stabilization, mortar mixes, and plaster. It enhances workability, durability, and resistance to sulfates, especially in road and foundation engineering.
3. Flue Gas Treatment
slaked lime plays a critical role in air pollution control. It is used to remove sulfur dioxide (SO₂), hydrochloric acid (HCl), and other acidic gases from industrial exhausts — a key step in reducing emissions and meeting environmental regulations.
4. Metallurgical Processes
In the steel and non-ferrous metals industries, slaked lime is utilized in ore processing, slag conditioning, and impurity removal. It contributes to higher product purity and better process efficiency.
5. Chemical Manufacturing
slaked lime serves as a key intermediate in the production of chemicals such as calcium stearate, calcium hypochlorite (bleaching powder), and other calcium-based compounds.
