calcination
n 1: the conversion of metals into their oxides as a result of
heating to a high temperature

Calcination \Cal`ci*na"tion\ (k[a^]l`s[i^]*n[=a]"sh[u^]n), n.
[F. calcination.]
[1913 Webster]
1. (Chem.) 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.
[1913 Webster]

2. The act or process of reducing a metal to an oxide or
metallic calx; oxidation.
[1913 Webster]

  • Calcination | Thermal Decomposition, Heating Oxidation | Britannica
    Calcination, the heating of solids to a high temperature for the purpose of removing volatile substances, oxidizing a portion of mass, or rendering them friable Calcination, therefore, is sometimes considered a process of purification A typical example is the manufacture of lime from limestone
  • Calcination - Wikipedia
    Calcination is thermal treatment of a solid chemical compound (e g mixed carbonate ores) whereby the compound is raised to high temperature without melting under restricted supply of ambient oxygen (i e gaseous O 2 fraction of air), generally for the purpose of removing impurities or volatile substances and or to incur thermal decomposition
  • Calcination- Process, Examples and Applications in Industries.
    Industrial calcination involves subjecting raw materials to elevated temperatures to bring about chemical or physical changes These raw materials, after initial preparation steps like grinding or sizing, undergo the calcination process, which typically involves heating in kilns or furnaces
  • Calcination - GeeksforGeeks
    Calcination is the process of heating a solid compound at a very high temperature in absence of oxygen or a limited supply of oxygen at controlled atmospheric pressure Calcination in other words also called as purification because it is used for the extraction of metals from its ore
  • What is Calcination? - FEECO International Inc.
    Calcination is a diverse thermal treatment in which the chemical separation of components gives producers the ability to remove volatile components, enhance product characteristics, remove crystalline water, and more
  • What is calcination? A Complete Guide to Thermal Treatment Processes
    Calcination is a heat treatment process where materials are heated to high temperatures, typically below their melting point, in the absence or limited supply of air or oxygen It is used to induce thermal decomposition, remove volatile substances, or cause phase transitions in materials
  • What is Calcination? - BYJUS
    Calcination is defined as the process of converting ore into an oxide by heating it strongly The ore is heated below its melting point either in absence of air or in limited supply This method is commonly used for converting carbonates and hydroxides to their respective oxides
  • What Is Calcination? A Guide To Thermal Treatment For Material . . .
    Calcination is a heat treatment process where materials are heated to high temperatures, just below their melting points, to induce thermal decomposition or remove volatile components The primary purposes of calcination include:
  • What Is Calcination? A Comprehensive Guide To Thermal Treatment . . .
    Common calcination methods include thermal decomposition, oxidation, reduction, and phase transition calcination The equipment used for calcination, such as muffle, reverberatory, or shaft furnaces, plays a critical role in achieving the required temperature and atmospheric conditions
  • Understanding Calcination: Process, Examples, and Differences from Roasting
    The calcination process involves heating solids at high temperatures, primarily to remove volatile substances, water, or to oxidize the substance Hence, it is also known as a purification process The term 'Calcination' originates from the Latin word 'Calcinare' which means “to burn lime”
