Calcium Hydroxide & Calcium Oxide – Essential Alkali Solutions for Industrial Efficiency and Environmental Sustainability.
Product Overview
Calcium hydroxide (Ca(OH)₂) and calcium oxide (CaO) are widely used alkaline materials known for their high reactivity and versatility. Calcium hydroxide, commonly referred to as hydrated lime, is a fine, white powder produced by reacting calcium oxide with water. Calcium oxide, or quicklime, is a highly reactive substance with excellent heat resistance and chemical stability. Both compounds play essential roles across various industries, from construction and wastewater treatment to agriculture and chemical manufacturing.
Key Features of Calcium Hydroxide And calcium Oxide
Reactive with Water
Calcium oxide reacts exothermically with water to form calcium hydroxide, which then dissolves slightly in water to create a suspension known as limewater.
High Purity & Stability
They are produced with minimal impurities, ensuring consistent performance across different applications.
Powdered or Granular Form
Both materials are available in different particle sizes to accommodate various industrial requirements.
Environmental Benefits
Widely used in pollution control and wastewater treatment to reduce environmental pollutants.
Common Advantages of Calcium Hydroxide And calcium Oxide
Versatile Industrial Applications
Used across multiple industries, including construction, steelmaking, chemical processing, agriculture, and environmental remediation.
Effective Acid Neutralization
Their strong alkaline properties make them highly effective in neutralizing acidic compounds in industrial waste, soil conditioning, and water treatment.
Enhances Material Properties
Integral to cement, plaster, and mortar formulations, improving durability, setting time, and strength in construction materials.
Supports Environmental Protection
Utilized in processes like flue gas desulfurization, wastewater treatment, and air purification to help reduce pollution.
Applications of Calcium Hydroxide And calcium Oxide
Lubricant Additives
Calcium Hydroxide and Calcium Oxide are key components in the production of lubricant detergent and dispersant additives. Calcium hydroxide (Ca(OH)₂) is commonly used as a raw material to react with organic acids, forming calcium sulfonates and calcium phenates—effective detergents that help keep engine components clean by preventing deposits, sludge, and varnish. These calcium-based detergents also neutralize acidic by-products from combustion, protecting internal engine parts and enhancing lubricant performance. Meanwhile, calcium oxide (CaO) plays a crucial role in adjusting pH levels during the synthesis process, ensuring optimal conditions for producing consistent, high-quality additives. Together, these compounds are vital in engine oil additive formulations, contributing to cleaner engines and longer lubricant life.
Water and Wastewater Treatment
n water treatment systems, calcium hydroxide is used to adjust pH levels by neutralizing acidic water, creating an environment that enhances coagulation and precipitation of impurities. It effectively removes dissolved heavy metals such as lead, cadmium, and arsenic by converting them into insoluble forms, which are easier to filter out. Additionally, calcium hydroxide improves water clarity by promoting the aggregation of fine particles into larger flocs. In municipal and industrial wastewater treatment, it helps meet environmental discharge standards and improves overall treatment efficiency.
Steel Manufacturing
Calcium oxide, also known as quicklime, plays a vital role in the metallurgical industry, particularly in the production of steel. It acts as a fluxing agent in blast furnaces and electric arc furnaces, where it reacts with impurities such as silica, phosphorus, and sulfur to form a slag. This slag floats on top of the molten steel, allowing easy removal of contaminants and improving the purity and mechanical properties of the final steel product. Its use helps enhance product quality, reduce energy consumption, and increase operational efficiency in steel mills.
Chemical Industry
Both calcium hydroxide and calcium oxide are widely used in the synthesis of various industrial chemicals. They serve as precursors for producing calcium carbonate, calcium chloride, calcium stearate, and other calcium-based compounds. These derivatives have broad applications across industries—from food processing and pharmaceuticals to rubber, plastics, and paper manufacturing. Calcium compounds also function as pH regulators, neutralizing agents, and catalysts in a wide range of chemical reactions, making them indispensable in large-scale chemical production.
Customer Reviews
Sam J
I bought calcium hydroxide to purify my well water, and it has been very effective in reducing acidity. The water tastes much cleaner now, and I feel safer using it for cooking and drinking.
Sarah L
I used calcium oxide for a small construction project at home, and the quality was excellent. It helped strengthen the mortar mix, and the final structure feels really solid.
John D
I added calcium hydroxide to my fish pond as recommended, and it helped clear up the water and stabilize the pH. My fish seem healthier, and algae growth has decreased significantly.
Amy S
I use calcium hydroxide for preparing traditional corn tortillas, and it works perfectly! The quality is great, and it helps soften the corn for grinding. Definitely a good product for cooking purposes.
FAQ
A1: Calcium oxide (quicklime) is a highly reactive compound that releases heat when mixed with water, forming calcium hydroxide (hydrated lime), which has a more controlled reactivity.
