Chemically, calcium carbide is CaC2, a substance resembling dark grey limestone gravel which, when combined with water, produces flammable acetylene gas Before electric lights, carbide was used by miners as fuel for their lamps (carbide lamps are still frequently called "miners lamps"), hence the term "miners grade" in reference to smaller chunks which burn easily in a carbide lamp It is still the fuel of choice for many European and U S cavers due to its heat producing properties and the quality (due to wavelength) of the light it produces
A very hard and durable compound used to make router cutters This is either brazed onto steel shoulders or produced as an integral solid carbide cutter Carbide requires careful handling and storage as it can be brittle
Carbide alloy is composed of Cobalt and Tungsten This alloy gives saw blades and router bits longer lasting tips, sharper cutting edges, and greater impact resistance
A Compound of metal and carbon Chromium carbide at grain boundaries of austenitic stainless steels causes poor corrosion resistance This carbide may result from welding or improper annealing
Inorganic compound, any of a class of chemical compounds in which carbon is combined with a metal or semimetallic element. The nature of the second element (its position in the periodic table) determines the carbide's type of bonding and its properties. Calcium carbide is useful as a source of acetylene. Carbides of tungsten, silicon (see Carborundum), and boron, called refractory carbides, are extremely hard, remain stable when heated, and have a high melting point and chemical resistance. They are used as abrasives and in cutting tools, as furnace linings, and in other high-temperature applications. Iron carbide (cementite) is an important constituent of steel and cast iron
A compound of carbon with one or more metallic elements Carbon (Chemical symbol C) - Element No 6 of the periodic system; atomic weight 12 01; has three allotropic modifications, all non-metallic Carbon is preset in practically all ferrous alloys, and has tremendous effect on the properties of the resultant metal Carbon is also an essential compound of the cemented carbides Its metallurgical use, in the form of coke, for reduction of oxides, is very extensive Carbon Free Metals and alloys which are practically free from carbon Carbon Range In steel specifications, the carbon range is the difference between the minimum and maximum amount of carbon acceptable
