Product Description
Calcium Oxide(CaO)
Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound.
It is a white, caustic and alkaline crystalline solid at room temperature.
Molecular formula: CaO
CAS: 1305-78-8
Appearance: White powder
H.S. Code:2825909000
Properties:
Colorless or white block or powder. In the air absorb carbon dioxide and water.The relative density of 320-3.38, melting point 2614 degree, boiling point 2850 degree. In water is generated with calcium hydroxide and give off a lot of heat, slightly soluble in water, soluble in acid. Corrosive. To eyes, respiratory system and skin irritation.
