Overview
Quicklime powder is a finely ground form of calcium oxide (CaO), produced by heating limestone (calcium carbonate) to high temperatures in a process called calcination. It is a versatile industrial material with applications in construction, metallurgy, and chemical processing. The powder form allows for easier handling and more uniform mixing in various industrial processes. Quicklime powder is known for its high reactivity, particularly with water, which makes it useful in a range of chemical reactions. Its alkaline nature also makes it effective in neutralizing acids and treating wastewater. The powder is typically white to grayish-white, depending on the impurities present in the original limestone.
Physical and Chemical Properties
Quicklime powder has a high melting point of 2572°C and a boiling point of 2850°C, making it stable under extreme temperatures. Its density is approximately 3.34 g/cm³, and it is highly reactive with water, producing calcium hydroxide and releasing heat in an exothermic reaction. This property is utilized in various industrial applications, including soil stabilization and waste treatment. The powder is hygroscopic, meaning it absorbs moisture from the air, which can lead to clumping if not stored properly. It is also alkaline, with a pH of around 12-13 when mixed with water. These properties make it a valuable agent in chemical processes where pH adjustment or heat generation is required.
Main Applications
Quicklime powder is widely used in the construction industry for soil stabilization and as a key ingredient in mortar and plaster. Its ability to react with water and harden makes it ideal for binding materials together. In metallurgy, it is used as a flux to remove impurities during the smelting of metals like iron and copper. In chemical processing, quicklime powder is employed in the production of calcium-based chemicals, such as calcium hydroxide and calcium carbonate. It is also used in water treatment to adjust pH levels and remove contaminants. Additionally, it plays a role in waste treatment, where it helps neutralize acidic waste and reduce odors.
Safety and Storage
Quicklime powder is highly caustic and can cause severe skin burns and eye damage upon contact. Proper personal protective equipment (PPE), including gloves, goggles, and protective clothing, should always be worn when handling the material. Inhalation of dust can also irritate the respiratory system, so a dust mask or respirator is recommended. Storage conditions are critical to maintaining the quality of quicklime powder. It should be kept in a dry, cool place away from moisture to prevent premature reaction with water. Containers should be sealed tightly to minimize exposure to air, which can lead to clumping and reduced effectiveness.
B2B Procurement Guide
When procuring quicklime powder, B2B buyers should pay close attention to purity levels, which typically range from 85% to 95%. Higher purity grades are essential for applications requiring precise chemical reactions. Particle size is another critical factor, as finer powders react more quickly and uniformly. Buyers should also consider the supplier's reliability and the consistency of product quality. Bulk purchases often come with cost advantages, but storage capacity and shelf life should be factored in. It's advisable to request samples and conduct tests before committing to large orders. Prices vary based on purity, quantity, and market conditions, with reference prices ranging from $50 to $150 per metric ton.
