What's the difference between calcine and melting?

Calcine


Definition:

  • (v. i.) To reduce to a powder, or to a friable state, by the action of heat; to expel volatile matter from by means of heat, as carbonic acid from limestone, and thus (usually) to produce disintegration; as to, calcine bones.
  • (v. i.) To oxidize, as a metal by the action of heat; to reduce to a metallic calx.
  • (v. i.) To be converted into a powder or friable substance, or into a calx, by the action of heat.

Melting


Definition:

  • (p. pr. & vb. n.) of Melt
  • (n.) Liquefaction; the act of causing (something) to melt, or the process of becoming melted.
  • (a.) Causing to melt; becoming melted; -- used literally or figuratively; as, a melting heat; a melting appeal; a melting mood.

Example Sentences:

  • (1) We’re learning to store peak power in all kinds of ways: a California auction for new power supply was won by a company that uses extra solar energy to freeze ice, which then melts during the day to supply power.
  • (2) The melting profile exhibited two transitions--one at about 35 degrees C and one above 50 degrees C. Our spectral data showed that helices I and II were stable during the first transition, and agreed with other data that helix III was the most likely helix to have melted.
