About Quick Lime Powder/calcium oxide powder
Quick Lime Powder
Calcium Oxide (CaO) having CAS-No.: 1305-78-8, commonly known as Quicklime Powder/ Burnt Lime/ Unslaked Lime, is usually made by the thermal decomposition of materials, such as Limestone or Seashells, that contain Calcium Carbonate (CaCO3; mineral calcite) in a lime kiln. This is accomplished by heating the material to above 825 C (1,517 F),[6] a process called calcination or lime-burning, to liberate a molecule of carbon dioxide (CO2), leaving to form "Quicklime Powder".
Exceptional Physical and Chemical PropertiesQuick Lime Powder is recognized for its high melting point, substantial purity, and snow-white appearance. As an amorphous white solid, it serves as a highly reactive material, easy to store at room temperature, and is free from any poisonous characteristics. Its basic nature makes it ideal for neutralizing acids and diverse industrial processes.
Versatile Industrial ApplicationsThis product finds application in various sectors, including metallurgy, construction, chemical manufacturing, and environmental treatment. Due to its solubility in water and glycerol and unique reactivity, Quick Lime Powder is used for pH regulation, wastewater treatment, and as a flux in steel production. Its efficient performance enhances productivity across industries.
Safe Storage and Easy HandlingQuick Lime Powder must be stored at room temperature in airtight containers to preserve its reactivity and prevent moisture absorption. Although non-toxic and odorless, it is crucial to avoid prolonged exposure to the air and water before use to maintain its effectiveness. With proper handling, its shelf life extends up to 180 days.
FAQ's of Quick Lime Powder/calcium oxide powder:
Q: How is Quick Lime Powder (calcium oxide) produced?
A: Quick Lime Powder is created by heating calcium carbonate or limestone to temperatures between 1250C and 1400C in kilns. This process decomposes the material, resulting in quicklime (calcium oxide) and carbon dioxide as byproducts.
Q: What are the main industrial uses of Quick Lime Powder?
A: Quick Lime Powder is primarily used in metallurgy as a flux, for pH adjustment in water and wastewater treatment, in construction for mortar and plaster, and in chemical industries for producing various compounds. Its high reactivity and strong basic nature make it a valuable industrial material.
Q: When should Quick Lime Powder be used after manufacturing?
A: For optimal performance and reactivity, Quick Lime Powder should be used within 180 days from the manufacturing date, as stated by its specified shelf life.
Q: Where should Quick Lime Powder be stored to maintain quality?
A: Quick Lime Powder should be stored at room temperature in airtight containers away from moisture and carbon dioxide to preserve its purity and reactive properties.
Q: What are the benefits of using Quick Lime Powder in industrial processes?
A: Quick Lime Powder offers benefits such as effective acid neutralization, efficient fluxing in metallurgy, enhancement of construction materials, and purification of water and air. Its versatility and cost-effectiveness contribute significantly to industrial efficiency.
Q: Is Quick Lime Powder safe to handle and use?
A: Yes, Quick Lime Powder is non-poisonous and odorless. However, it is caustic in nature, so appropriate safety gear such as gloves and eye protection should be used when handling to prevent skin or eye irritation.
