What's the difference between calcination and thermal?

Calcination


Definition:

  • (n.) The act or process of disintegrating a substance, or rendering it friable by the action of heat, esp. by the expulsion of some volatile matter, as when carbonic and acid is expelled from carbonate of calcium in the burning of limestone in order to make lime.
  • (n.) The act or process of reducing a metal to an oxide or metallic calx; oxidation.

Thermal


Definition:

  • (a.) Of or pertaining to heat; warm; hot; as, the thermal unit; thermal waters.
