your mixing two chemicals together so of course its a chemical change
Mixing flake graphite with oil is a physical change, not a chemical change. The graphite particles remain unchanged chemically, they simply disperse in the oil. No new substances are forming.
The composition of backfilling compound for chemical earthing typically includes a mixture of bentonite, salt, and graphite. Bentonite is used for enhancing conductivity, while salt helps in maintaining low resistance levels. Graphite is added to improve the overall performance and longevity of the earthing system.
Rusting is a chemical process when the surface of a metal becomes attacked by elements in air or water and it asorbs oxygen (or sometimes sulfur) to become a compound of it. However, many materials do not rust, because the modified surface so formed does not peel or flake-off, exposing more of it for this chemistry to repeat its action.Thus rusting is a very chemical change (as peeling of the surface is not really defined as a physical change).
The paint began to flake off.In Britain, Flake is a kind of chocolate bar.She choked on a chocolate flake in her mocha.
I can give you several sentences.The snow flake melted instantly.I found a flake of obsidian on the ground.That rock will flake easily when struck.You could also use the slang meaning of someone who is eccentric or odd. "That fellow is a real flake!"
ParaDiChloroBenzene is commonly found in crystal form, appearing as colorless or white crystals. It is rarely found in flake form.

In nature, graphite is found as flake, vein, or amorphous form. Graphite is polymorph of carbon. Graphite is a non-metal that is a conductor of electricity.
Graphite's atomsare arranges in layers, like shest of hexagonal tiles and wave weak bonds.
Graphite appears naturally in three forms: amorphous, which is the last stage of the coalification process; crystalline flake, which is used in brake linings and pencils; and lump, used mostly in batteries

Physical change: bending. Chemical change: Rusting (oxidation). An example of both in one item: A wrought iron fence was heated and bent into a decorative pattern. After 20 years, the fence shows evidence of deep rusting, especially on decorative curves.
