oxide has the chemical formula CaO and is a white crystalline substance.
Because calcium oxide does not occur naturally, its production is generally
from calcium carbonate or limestone. There are many commercial uses for this
compound because it readily forms solutions with other substances like
silicates. Some other uses of calcium oxide in other industries include the
making of porcelain, the preparation of bleaching powder and the purification of
iron and steel industries utilizes calcium oxide as a flux in the purification
of scrap iron or steel. Calcium oxide can remove different impurities, such as
phosphorus and silica from scrap materials. This process is important for
refining and making steel products.
agriculture and gardening, calcium oxide has applications as a fertilizer to
treat acidic soil. Another commercial application of calcium oxide is in the
construction industry that utilizes it in cement and mortar. Some other uses of
calcium include as a water softener, in the making of glass and in the
treatment of wastewater. METALLURGY, Steel Manufacture, Steel Products
