There are different grades of magnesia carbon brick. And it is usually used for the lining and tap hole of steelmaking converter, the sidewall and slag line of high power electric ARC furnace and ladle slag line.
i think it is chemical but it may be physical.
Carbon is a chemical property because it describes how carbon interacts with other substances to form new compounds. Physical properties, on the other hand, are characteristics that can be observed or measured without changing the composition of the substance.
chemical change
The word equation for heating magnesia alba (magnesium carbonate) can be expressed as: Magnesia Alba (magnesium carbonate) → Magnesium Oxide + Carbon Dioxide + Water. This reaction occurs when magnesia alba is heated, resulting in the decomposition of magnesium carbonate into magnesium oxide, carbon dioxide gas, and water vapor.
No, dissolving solutes in a solvent is always a physical change!
Black is the physical color of carbon, not its chemical property.

Frozen carbon dioxide is still carbon dioxide, so it is a physical change.

Carbon that cannot be decomposed is a chemical property. It is related to the chemical bonds and composition of the substance, indicating that the carbon atoms are tightly held together in a way that resists decomposition through physical means.

Carbon dioxide (CO2) is a chemical compound consisting of one carbon atom bonded to two oxygen atoms. It is a chemical property because it describes the composition and arrangement of atoms in a substance. However, in terms of physical properties, carbon dioxide is a colorless, odorless gas at standard temperature and pressure.
