 (kăl-sīn′, kăl′sīn′)
v. cal·cined, cal·cin·ing, cal·cines
v.tr.
1. To heat (a substance) to a high temperature but below the melting or fusing point, causing loss of moisture, reduction or oxidation, and the decomposition of carbonates and other compounds.
2. To convert (liquid material, especially radioactive wastes) to granular solids by drying at very high temperatures.
v.intr.
To be calcined.
n.
A substance produced by calcining.

[Middle English calcinen, from Old French calciner, from Medieval Latin calcīnāre, from Late Latin calcīna, quicklime, from Latin calx, calc-, lime; see calx.]
