Calcination Wikipedia

Calcination reactions usually take place at or above the thermal decomposition temperature (for decomposition and volatilization reactions) or the transition temperature (for phase transitions). This temperature is usually defined as the temperature at which the standard Gibbs free energy for a particular calcination reaction is equal to zero. In limestone calcination, a decomposition process that occurs at 900 to 1050ºC, the chemical reaction is
