Wikipedia
Authorities differ on the meaning of calcination (also referred to as calcining). The IUPAC defines it as 'Heating to high temperatures in air or oxygen'. However calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decomposition. A calciner is a steel cylinder that rotates inside a heated furnace and performs indirect high-temperature processing (550-1150 °C, or 1000-2100 °F) within a controlled atmosphere.
