Sep 28, 2011 Calcium oxide is used as a refractory material as a flux in steelmaking as a binding agent in building, pulp and paper manufacture, sugar refining, and leather tanning as the raw material for chlorinated lime bleaching powder, and as a soil treatment in agriculture (Encyclopedia of Occupational Health and Safety, Vol. 2, p. 1234, International Labour Office 1983).
Calcium oxide (CaO), commonly known as burnt lime, lime or quicklime, is a widely used chemical compound. It is a white, caustic and alkaline crystalline solid. As a commercial product lime often also contains magnesium oxide, silicon oxide and smaller amounts of aluminium oxide and iron oxide.
Jul 14, 2018 Properties of Calcium Oxide. Quick lime is an amorphous white solid with a high melting point of 2600 . It is a very stable compound and withstands high temperatures. In the presence of water, it forms slaked lime. This process is called the slaking of lime. CaOH2O Ca (OH)2.
Calcium carbonate is white in color, though impurities may lend color to rocks and minerals. The carbonates are chalky in consistency. In fact, chalk is one variety of limestone, though modern classrooms use chalk made of gypsum (calcium sulfate). Lime (calcium oxide) is produced by heating limestone or seashells (calcium carbonate).
The production of the calcium oxide is complete. Make sure the calcium oxide is stored in a tightly sealed container because calcium oxide will absorb CO2 from the air producing calcium carbonate all over again. If calcium hydroxide is preferred, simply drop the calcium oxide stones into water. The calcium oxide stones should sputter and ...
