The main use for calcium carbide is in
the production of the flammable gas acetylene.
 When any grade of calcium carbide
comes into contact with water, a chemical reaction immediately
begins, which yields two new compounds, one of which is
acetylene, a very useful flammable gas. This is the principal
modern use of calcium carbide.
Countries such as China use large amounts of acetylene as an
industrial fuel, mainly because it is cheaper to make and use
domestically than to import petroleum for the same purpose. Oddly
enough, acetylene can also be used to speed up the ripening of
fruit, in the same way that ethylene is used.
Another use of calcium carbide is in
the making of some types of fertilizer. Calcium
cyanamide is one of these, and is produced when
calcium carbide reacts with
nitrogen at high
temperatures. Some steelmaking processes also require the use of
calcium
 One of the older uses of this material was in a device
called the carbide lamp. This
was a type of lamp that took advantage of the fact that water and
calcium carbide react together to make
acetylene. These lamps were used in mines beginning in the late
*9th century. The open flame produced by the burning acetylene in
the lamp ruled out its use in coal mines, but miners of tin,
copper and slate were able to
benefit from its use.
