Activated carbon has the effect of heat conduction, the oxidation process of activated carbon can be successfully completed because activated carbon can absorb water in the air. When heated, the charcoal will expand, and holes will appear between the carbon atoms. The surface area of each pound of activated carbon can be increased to the same size as six football fields, so these gaps can completely absorb water.

Iron powder

Iron powder will react with oxygen in the air to form iron oxide, which will release heat when the iron is corroded. The heat released will make the temperature of iron powder rise, generally to about 68 ℃.

sodium chloride

Many cities with more snowfall will use sodium chloride for deicing, and the cars we park outside are often corroded by sodium chloride. In the warm baby principle here, sodium chloride can make iron powder corrode.
