Calcium Oxide Powder 90% Extra Pure by Loba Chemie (India) is a high-purity form of calcium oxide (CaO). It is commonly used in a variety of chemical, industrial, and laboratory applications. It is also known as quicklime and is typically employed in processes like water treatment, metal production, and as a desiccant or drying agent.

Key Features of the Calcium Oxide:

• Purity: 90% Extra Pure grade, which makes it suitable for laboratory and industrial use where high purity is required.
• Appearance: A fine, white powder.
• Chemical Composition: Primarily made up of calcium oxide (CaO), with minimal impurities.
• Packaging: Usually available in sealed containers to maintain its purity and prevent moisture absorption, as calcium oxide is hygroscopic.

General Applications:

• Water and wastewater treatment (flocculation and pH adjustment).
• In the production of cement, steel, and glass.
• In the manufacturing of chemicals like calcium hydroxide (slaked lime).
• For soil stabilization in agriculture and construction.
• As a drying agent in laboratory settings.

Handling and Safety:

• Storage: Keep in a cool, dry place in tightly sealed containers to avoid moisture absorption and reactions with air.
• Safety: It can be corrosive and should be handled with care. Use protective gloves, goggles, and a dust mask to prevent irritation to the skin, eyes, and respiratory system.
• Reactivity: Calcium oxide reacts exothermically with water to form calcium hydroxide (slaked lime). Therefore, it should be kept away from moisture.
