Oxide For Making Refractory Materials
Calcium oxide (CaO), commonly known as quicklime or burnt lime, is
a widely used chemical compound. It is a white, caustic, alkaline,
crystalline solid at room temperature. The broadly used term lime
connotes calcium-containing inorganic materials, in which
carbonates, oxides and hydroxides of calcium, silicon, magnesium,
aluminium, and iron predominate. By contrast, quicklime
specifically applies to the single chemical compound calcium oxide.

Calcium Oxide/ quicklime Use:
Light: When quicklime is heated to 2,400 °C (4,350 °F), it emits an
intense glow. This form of illumination is known as a limelight,
and was used broadly in theatrical productions before the invention
of electric lighting.
Cement: Calcium oxide is a key ingredient for the process of making
As a cheap and widely available alkali. About 50% of the total
quicklime production is converted to calcium hydroxide before use.
Both quick- and hydrated lime are used in the treatment of drinking
Petroleum industry: Water detection pastes contain a mix of calcium
oxide and phenolphthalein. Should this paste come into contact with
water in a fuel storage tank, the CaO reacts with the water to form
calcium hydroxide. Calcium hydroxide has a high enough pH to turn
the phenolphthalein a vivid purplish-pink color, thus indicating
the presence of water.
Paper: Calcium oxide is used to regenerate sodium hydroxide from
sodium carbonate in the chemical recovery at Kraft pulp mills.
Plaster: There is archeological evidence that Pre-Pottery Neolithic
B humans used limestone-based plaster for flooring and other
uses.Such Lime-ash floor remained in use until the late nineteenth
Chemical or power production: Solid sprays or slurries of calcium
oxide can be used to remove sulfur dioxide from exhaust streams in
a process called flue-gas desulfurization.
Mining: Compressed lime cartridges exploit the exothermic
properties of quicklime to break rock. A shot hole is drilled into
the rock in the usual way and a sealed cartridge of quicklime is
placed within and tamped. A quantity of water is then injected into
the cartridge and the resulting release of steam, together with the
greater volume of the residual hydrated solid, breaks the rock
apart. The method does not work if the rock is particularly hard.
