Lime (calcium oxide) fuses only at the highest heat of the electric furnace, but it breaks down into dust.
This calcium oxide, commonly known as “quick lime,” is the substance desired in clarification.
It will be seen that the products are acetylene gas and calcium oxide or lime.
Thus when calcium carbonate dissociates under the influence of heat, calcium oxide and carbon dioxide are formed.
calcium oxide is a compound left after the burning of limestone, and is known as fresh burned lime, or quick lime.
calcium oxide is also good but zinc oxide must be used sparingly as it is apt to suffer if overfired.
With lime (calcium oxide) and soda (which yields sodium oxide) we get soda-lime glass (common window glass).
Wood ashes are also a good source of lime, being about one-third calcium oxide.
He thought that the lime (calcium oxide) would act on the coal (carbon) to form calcium and carbon monoxide.
In what respects does aluminium oxide differ from calcium oxide in properties?
calcium oxide n.
A white, caustic, lumpy powder used in analytical and manufacturing procedures, in glassmaking, in waste treatment, in insecticides, and as an industrial alkali. Also called lime3.
|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.
