thermal decomposition of limestone

  • Thermal decomposition - Wikipedia

    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

    Abstract: In this paper, decomposition reaction of limestone and precipitate calcium carbonate (PCC) was investigated, using thermo gravimetric analysis technique. All e×periments were performed in isothermal conditions, within a temperature range of 973-1173 K, with main diameters of granules: 63μm, 180μm, and

  • Thermal decomposition of calcium carbonate- Learn Chemistry

    Calcium carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The calcium oxide (unslaked lime) is dissolved in water to form calcium hydroxide (limewater). Bubbling carbon dioxide through this forms a milky suspension of calcium carbonate.
