What is Thermal Decomposition?
A chemical reaction in which a compound breaks down into simpler substances upon heating. Examples include the decomposition of calcium carbonate (CaCO₃ → CaO + CO₂) and metal carbonates. Thermal stability of compounds depends on the strength of the bonds being broken.

A chemical reaction in which a compound breaks down into simpler substances upon heating. Examples include the decomposition of calcium carbonate (CaCO₃ → CaO + CO₂) and metal carbonates. Thermal stability of compounds depends on the strength of the bonds being broken.
Thermal decomposition is used industrially to produce quicklime (CaO) from limestone. It is used in the production of metals from metal oxides and carbonates. Thermal decomposition of peroxides and azo compounds generates free radicals used as initiators in polymerisation.
Thermally unstable compounds (peroxides, azides, diazonium salts) can decompose explosively. Storage at controlled low temperatures is required for heat-sensitive reactive compounds. Thermal decomposition can also generate toxic gases.
The formula or notation for Thermal Decomposition is: AB → A + B (heat); e.g., CaCO₃ → CaO + CO₂
