Upon calcination, the calcite (CaCO 3) peaks almost totally disappeared in the calcined limestone sample due to its decomposition to form lime (CaO), whose peaks became more apparent. This indicated that the calcination procedure with the target temperature of 950 °C effectively decomposed most of the calcite in the raw material.
