    Thermal decomposition, or thermolysis, is a chemical decomposition caused by heat. The decomposition temperature of a substance is the temperature at which the substance chemically decomposes. The reaction is usually endothermic as heat is required to break chemical bonds in the compound undergoing decomposition.

  • Thermal decomposition of calcium carbonate (13K)

    Limestone has many different uses, such as for concrete, cement and glass. It can also be chemically changed into slaked lime and quicklime. Thermal decomposition is when a substance is heated strongly to produce at least two products. In this case, we are heating a carbonate, which means that the ...

    Calcination of Limestone . Calcination or calcining is a thermal treatment process to bring about a thermal decomposition. The process takes place below the melting point of the product. The name calcination is derived from the Latin word 'Calcinare' which mean to burn lime. Limestone is a naturally occurring mineral.
