calcium oxide
A white solid compound that has a very high melting point and reacts with water to form calcium hydroxide. It is often prepared commercially by heating limestone. Calcium oxide is used as an alkali for treating acidic soils and in manufacturing steel, paper, and glass, and it is the main component of lime. Chemical formula: CaO.
A white, lumpy, caustic powder made of calcium oxide sometimes mixed with other chemicals. It is made industrially by heating limestone, bones, or shells. Lime is used as an industrial alkali, in waste treatment, and in making glass, paper, steel, insecticides, and building plaster. It is also added to soil to lower its acidity.
