Properties: White crystalline powder, can absorb the carbon dioxide in the air generated calcium carbonate. Soluble in acid, insoluble in water, reacts with water calcium hydroxide. Quicklime as a clear pond of drugs commonly used to good effect. Be able to eliminate its harmful aquatic plants and animals and the disease-causing parasites and pathogens; Clarify the water, so that the water quality variable fertilizer; Stability of water was slightly alkaline.

Uses:
1. Used as analytical reagent, spectral analysis reagents, phosphor-solvent, vegetable oil bleaching agent, gas analysis for carbon dioxide absorbent, high-purity reagents
2. Used in semiconductor production in the extension, diffusion process.
3. Used in the manufacture of calcium carbide, soda ash, bleaching powder, etc.,
4. Used as building materials, refractories, desiccant and calcium fertilizer and soil conditioner.
