Overview
High purity lime, chemically known as calcium oxide (CaO), is a fundamental industrial chemical with a wide range of applications. It is produced by heating limestone (calcium carbonate) to high temperatures, a process known as calcination. The resulting product is a white, crystalline solid that is highly reactive, particularly with water. High purity lime is distinguished by its low levels of impurities, making it suitable for sensitive industrial processes. It is commonly used in steel production, water treatment, and chemical manufacturing, where its reactivity and alkaline properties are leveraged.
Physical and Chemical Properties
High purity lime is characterized by its high melting point (2572°C) and boiling point (2850°C), which make it stable under extreme conditions. Its density is approximately 3.34 g/cm³, and it reacts exothermically with water to form calcium hydroxide, releasing significant heat. The compound is highly alkaline and acts as a strong dehydrating agent. Its reactivity with acids and organic materials makes it useful in neutralizing acidic waste streams and in chemical synthesis. The purity of the lime is critical, as impurities can affect its performance in industrial applications.
Main Applications
High purity lime is indispensable in the steel industry, where it is used to remove impurities during the production process. It acts as a flux to separate slag from molten metal, ensuring high-quality steel output. In water treatment, lime is employed to adjust pH levels and remove heavy metals and phosphates. Chemical manufacturing relies on high purity lime for producing calcium-based compounds, such as calcium carbide and calcium hypochlorite. Additionally, it is used in construction for soil stabilization and in the production of mortar and plaster. Its versatility and reactivity make it a cornerstone of many industrial processes.
Safety and Storage
High purity lime is a corrosive substance that can cause severe burns upon contact with skin or eyes. Inhalation of dust particles can irritate the respiratory tract, necessitating the use of protective equipment such as gloves, goggles, and masks. Storage conditions are critical to maintaining the quality of high purity lime. It must be kept in a dry, well-ventilated area to prevent reaction with moisture, which can lead to caking and reduced reactivity. Containers should be tightly sealed and labeled appropriately to avoid accidental exposure.
B2B Procurement Guide
When procuring high purity lime, B2B buyers should prioritize suppliers with verified certifications and a track record of consistent quality. Key factors to consider include the lime's purity level, typically expressed as a percentage of CaO, and the presence of impurities such as magnesium oxide or silica. Packaging should be inspected for integrity, as exposure to moisture during transit can degrade the product. Bulk purchases may offer cost advantages, but buyers should ensure that storage facilities are equipped to handle large quantities safely. Price negotiations should factor in delivery costs and potential volume discounts.
