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 decomposition.

Using Limestone and Thermal Decomposition - Get Revising

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 ...
