DESCRIPTION

Calcium Oxide

English Name: calcium oxide

CAS No.: 1305-78-8

Molecular formula: CaO

Molecular weight: 56.08

EINECS No.: 215-138-9

Introduction: calcium oxide is an inorganic compound, commonly known as quicklime. The physical property is white powder on the surface. The impure powder is gray white. It is light yellow or gray when containing impurities and has hygroscopicity. Calcium oxide is an alkaline oxide, which is sensitive to humidity. Easy to absorb carbon dioxide and water from the air. It reacts with water to form calcium hydroxide and generates a large amount of heat, which is corrosive.

Chemical properties: White Cubic powder. Industrial products are often dark gray, light yellow or brown because they contain impurities such as magnesium oxide, alumina and iron oxide. Soluble in acid.

Uses: used in the manufacture of calcium carbide, soda ash, bleaching powder, etc., as building materials, refractory materials, desiccant, soil conditioner and calcium fertilizer

Typical Properties

It is used as building materials and metallurgical flux. It is the main raw material for the preparation of calcium hydroxide and various calcium compounds. It is also a cheap alkali in the chemical industry. It is widely used in pesticide, papermaking, food, petrochemical industry, tanning, wastewater purification and so on. It can also be used for drying ammonia in laboratory and alcohol dehydration.
