Talk:Calcination - Wikipedia

However the reference that was there to calcining 'sulfates' is surely wrong. I have altered this to sulfides. Peterkingiron 17:05, 13 January 2007 (UTC) No, no. Driving off sulfur dioxide from sulfides is not calcination. That's a roasting process: MeS + O2 = MeO + SO2. Roasting is distinguished from calcining by there being a gas-solid reaction.

Low-temperature magnetic properties of hematite nanorods, prepared by both iron−water vapor reactions (sample 1) and hydrothermal methods (sample 2), were studied by superconducting quantum interference device (SQUID) magnetometry. The Morin transition temperature was found to be 122 K in hematite nanorod sample 1, and an unexpected phenomenon was found under an applied field of 10 Oe.

Calcination - Wikipedia

The process of calcination derives its name from the Latin calcinare (to burn lime) due to its most common application, the decomposition of calcium carbonate to calcium oxide and carbon dioxide, in order to create cement.The product of calcination is usually referred to in general as "calcine", regardless of the actual minerals undergoing thermal treatment.
