calcination 中文解釋 wordnet sense Collocation Usage Collins Definition
  1. the conversion of metals into their oxides as a result of heating to a high temperature
  2. Calcination (also referred to as calcining) is a thermal treatment process applied to ores and other solid materials in order to bring about a thermal decomposition, phase transition, or removal of a volatile fraction. ...
  3. Calcinate (Eastern Lombard: Calsinàt) is a town and comune in the province of Bergamo, Lombardy, Italy. Its economy is mostly based on industry.
  4. The process of calcining - heating a substance to a high temperature, but below its melting point, to bring about thermal decomposition
  5. (calcined) converted by calcination
  6. (Calcined) Oxidized by heating.
  7. (Calcined) Term used to describe bone that has been so thoroughly heated that all moisture and grease is oxidized or driven off, leaving only white, easily crumbled pieces. ...
  8. (Calcining) Burning: Enough heat to cause disintegration, or total fusion.
  9. (Calcining) To calcine a substance is to heat it so that it will break down into small particles or into a powder, or to drive of volatile substances.  Lime kilns are calcining furnaces, for example, as are coke ovens.  Other substances are calcined, as well. ...
  10. combusting in high heat to ashes in the presence of calcium; produces CaCO3 (aka calcite or limestone)
  11. The action of fire on mineral substances in which the reactants (a) often lose a noticeable amount of weight, (b) acquire a white color, (c) become friable (easily crumbled or pulverized). Almost always, a very high heat is employed.
  12. A process in which a material is heated to a high temperature without fusing, so that hydrates, carbonates, or other compounds are decomposed and the volatile material is expelled.
  13. Decomposition due to the loss of bound water and carbon dioxide.
  14. The process by which raw limestone is converted to quicklime by heating at temperatures between 900 - 1000 degrees C. During the process CaCO3 splits into calcium oxide (CaO) and carbon dioxide (CO2).
  15. Heating ores, concentrates, precipitates, or residues to decompose carbonates, hydrates, or other compounds.
  16. The first operation in alchemical transformation. It is denoted by the symbol for the first sign of the zodiac, Aries.
  17. Cremation from heat rather than flames.
