carbides, plural;
  1. A binary compound of carbon with an element of lower or comparable electronegativity

  2. Calcium carbide (CaC2), used to generate acetylene by reaction with water and formerly used in portable lamps
    • - a carbide lamp

  1. a binary compound of carbon with a more electropositive element
  2. In chemistry, a carbide is a compound composed of carbon and a less electronegative element. Carbides can be generally classified by chemical bonding type as follows: (i) salt-like, (ii) covalent compounds, (iii) interstitial compounds, and (iv) "intermediate" transition metal carbides. ...
  3. Any binary compound of carbon and a more electropositive element; The polyatomic ion C2^2−, or any of its salts; The monatomic ion C^4−, or any of its salts; A carbon-containing alloy or doping of a metal or semiconductor, such as steel; Tungsten carbide; trivial name for calcium carbide ( ...
  4. A compound of carbon with one or more metallic elements.
  5. A hard, sharp carbon/iron material used where a very hard material is needed such as in machining or drilling steel. Spyderco uses carbide to make the glass breaking tip found on the C79 Assist model.
  6. 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.
  7. Chemically, calcium carbide is CaC2, a substance resembling dark grey limestone gravel which, when combined with water, produces flammable acetylene gas. ...
  8. An extremely hard, wear resistant metal made from tungsten and carbon, used in the manufacture of cutting tools.
  9. calcium carbide Ca2C, it reacts with water to form the gas acetylene used as a lighting source by cavers and miners.
  10. A hard material made of compacted binary compounds of carbon and heavy metals, used to make tools that cut metal.
  11. A chemical compound combining carbon and another metallic element, normally produced for the purpose of providing wear resistance in steels, such as vanadium carbide or chromium carbide.
