    What Is calcination?Calcination ExamplesCalcination Process DescriptionCalcination ReactionsCalcination in simple words can be described as a process of heating some solid material or a substance in a controlled environment. Usually in the process, the temperature is also regulated. Calcination is done to bring about some change in the substance physical or chemical constitution. During calcination, solids are heated at high temperatures. This is done to mainly remove volatile substances, water or oxidize the substance. This process is also sometimes described as a purification process. The word Calcination h
  • Gypsum Calcination - Innogyps

    Calcination is the practice of dehydrating gypsum into plaster or stucco through a batch or continuous process which includes heating the gypsum to evaporate the crystalline water. Typically, free water is removed in an initial process at approximately 45℃ and crystalline bound water is removed in a second process at 120-180℃.

  • Calcination - Wikipedia

    OverviewIndustrial processesReactionsAlchemy

    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 (limestone) to calcium oxide (lime) 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. Calcination is carried out in furnaces or reactors (sometimes referred to as kilnsor calciners) of various designs including shaft furna
