Quick Lime

Quicklime: A Fundamental Material in Industry and Infrastructure

Quicklime, chemically known as calcium oxide (CaO), is one of the most essential and widely used materials in the industrial world. Its strong alkaline nature, high reactivity, and thermal stability make it indispensable across sectors such as metallurgyconstructionenvironmental engineering, and chemical processing.
At PARS HASTI ASIA, we are proud to supply premium-grade quicklime, manufactured with precision to meet the highest international standards and tailored to the specific requirements of various industries.

What is Quicklime?

Quicklime is produced by the thermal decomposition of limestone (calcium carbonate) in a kiln at temperatures exceeding 900°C. This process, known as calcination, releases carbon dioxide and leaves behind pure calcium oxide:
CaCO₃ (limestone) → CaO (quicklime) + CO₂
The result is a highly reactive white or grayish substance that must be handled carefully due to its caustic properties and exothermic reaction with water.

Key Applications of Quicklime

1. Metallurgical Industry
Quicklime is crucial in the production of steel and non-ferrous metals, where it acts as a fluxing agent to remove impurities such as silica, phosphorus, and sulfur from ores and slags. It improves yield and enhances the purity of the final metal products.
2. Construction and Civil Engineering
In construction, quicklime is used for soil stabilizationasphalt modification, and the production of aerated concrete blocks. It enhances soil strength and durability, particularly in foundation works and road construction.
3. Environmental Protection
Quicklime plays a vital role in air pollution control and waste treatment. It is used to neutralize acidic gases like sulfur dioxide (SO₂) in flue gas desulfurization systems and to treat industrial sludges and contaminated soils.
4. Chemical Industry
Quicklime is a key ingredient in the production of calcium hydroxide (hydrated lime)calcium carbide, and various inorganic chemicals. It is also used in pH regulation, chemical synthesis, and as a drying agent.
5. Paper, Sugar, and Glass Manufacturing
In the paper and pulp industry, quicklime is used in the causticizing process to regenerate sodium hydroxide. In sugar refining, it helps clarify juice by removing impurities. It is also used in glass production to enhance chemical durability.
