White Powder Lime
Overview
Calcium oxide powder, also known as quicklime, is a fundamental chemical compound with widespread industrial applications. It is produced by heating limestone (calcium carbonate) to high temperatures, a process known as calcination. The resulting white powder is highly reactive, especially with water, making it valuable in various chemical and construction processes. Quicklime has been used for centuries, dating back to ancient civilizations for mortar and plaster. Today, its applications extend to modern industries such as steel manufacturing, water treatment, and chemical synthesis. Its versatility and reactivity make it a critical material in many B2B supply chains.
Physical and Chemical Properties
Calcium oxide is a white, odorless crystalline solid with a high melting point of 2,572°C. It has a density of 3.34 g/cm³ and reacts vigorously with water, releasing heat and forming calcium hydroxide (slaked lime). This exothermic reaction is highly useful in industrial processes but requires careful handling. The compound is alkaline and can neutralize acids, making it valuable in pH adjustment applications. It is insoluble in organic solvents but reacts with acids to form salts. Its high reactivity with water necessitates dry storage conditions to prevent unintended reactions and degradation.
Main Applications
In construction, calcium oxide is a key ingredient in mortar and plaster, where it improves workability and durability. It is also used in soil stabilization and road construction to enhance the mechanical properties of subgrade materials. The steel industry relies on quicklime as a flux to remove impurities during smelting. In water treatment, it adjusts pH levels and softens water by precipitating dissolved minerals. Additionally, calcium oxide is used in chemical synthesis, such as producing calcium carbide and other industrial chemicals.
Safety and Storage
Calcium oxide is highly corrosive and can cause severe burns upon contact with skin or eyes. Inhalation of dust can irritate respiratory passages. Proper personal protective equipment (PPE), including gloves, goggles, and respirators, is essential when handling this material. Storage requires a cool, dry, well-ventilated area away from moisture and incompatible substances like acids and organic materials. Containers should be tightly sealed to prevent exposure to humidity, which can lead to heat generation and potential pressure buildup.
B2B Procurement Guide
When procuring calcium oxide powder, prioritize suppliers with a proven track record of quality and reliability. Verify the product's purity, typically ranging from 90% to 98%, depending on the application. Packaging should be durable and moisture-proof, such as sealed bags or bulk containers with desiccants. Bulk purchases often reduce costs, but ensure storage facilities can maintain dry conditions. Request material safety data sheets (MSDS) and certificates of analysis (CoA) to confirm compliance with industry standards. Lead times and logistics should align with your production schedules to avoid disruptions.
