Calcium oxide, calcium oxide), is a kind of inorganic compounds, its chemical formula is CaO, the common name for quick lime. Physical properties is the surface of white powder, no pure as the gray, containing impurities with pale yellow or gray, with moisture absorption.
Calcium oxide as basic oxide, is sensitive to wet. Easy to absorb carbon dioxide from the air and water. React with water to produce the calcium hydroxide (Ca (OH) 2) and generate a large amount of heat, corrosive.
Calcium oxide in the air for a long time exposure can absorb carbon dioxide into powder, calcium carbonate, no clear pond of disinfection effect. So, had better use now buy now quick lime, and choose to block is lighter, does not contain the impurities as well. If a exhaustless remaining lime mouth sealed plastic bags.
