Properties of GraphiteCrystal Benefits
Chemical Properties. Graphite is chemically inert to almost all chemicals. It burns completely when heated in oxygen to form carbon dioxide. However it fails to burn in air even if it is heated to high temperatures. When heated in the presence of concentrated sulfuric acid and potassium dichromate graphite gets oxidized to carbon dioxide.
