It is related to heating the sample (solid material, inorganic salt) to a specific temperature. The explanation needs to clarify the main differences between thermal decomposition and calcination.
Calcination is a heating treatment process to bring about a thermal decomposition, phase transition, or removal of a volatile fraction.
Dear Burhan
I am asking main differences between thermal decomposition and calcination. Burhan Ullah
Dear Dr. Aimal Khan These terminologies could be differentiated based on the outcomes of the process. Calcination is the decomposition of a substance at high temp (below melting point) releasing volatile components under limited or no air conditions. While thermal decomposition is the thermal breakdown of particular materials into different products (like oxidation).
Dear Dr. Shahid Zaman thank you for your response, but I still have concerns about this.
When calcium carbonate is heated, it changes into calcium oxide and carbon dioxide. The following is the chemical reaction:
CaCO3 → CaO + CO2
Which process is going there? Calcination or thermal decomposition. In both cases, the temperature keeps below the melting point.
OR, if possible, you can provide other examples to show a clear difference between them.
Thermal decomposition is the general process of breaking down a compound with heat, while calcination is a specific type of thermal decomposition that involves heating a substance to high temperatures in the absence of oxygen to produce oxides.
we say that thermal decomposition is broader term while calcination is a specific type of thermal decomposition
