Carbide | Article about carbide by The Free Dictionary
carbide, any one of a group of compounds that contain carbon and one other element that is either a metal, boron, or silicon. Generally, a carbide is prepared by heating a metal, metal oxide, or metal hydride with carbon or a carbon compound. Calcium carbide, CaC 2, can be made by heating calcium oxide and coke in an electric furnace; it reacts with water to yield acetylene and is an important

Brinell Hardness Test: a test for determining the hardness of a material by forcing a hard steel or carbide ball of specified diameter into it under a specific load. The result is expressed as the Brinell hardness nuer, which is the value obtained by dividing the applied load in kilograms by the surface area of the resulting impression in square millimeters.
