Oxygen production from thermal decomposition of metal oxides

On the other hand, some, if not most, metal oxides are extremely heat resistant. For example, once sintered at temperatures between $1700$ and $pu{2000°C}$, magnesium oxide $(ce{MgO})$ can be heated up to its melting point ($simpu{2800°C}$) without decomposition and can thus be used as a lining for heat sensors.

Thermal decomposition of calcium carbonate- Learn Chemistry

Calcium carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The calcium oxide (unslaked lime) is dissolved in water to form calcium hydroxide (limewater). Bubbling carbon dioxide through this forms a milky suspension of calcium carbonate.

What Is Thermal Decomposition? | Reference

Thermal decomposition is a chemical reaction where heat causes one substance to break into two or more different substances. The heat is used to break down the bonds holding the atoms of the original molecules together, so the reaction usually consumes more heat energy than it releases.
