Can graphite be made from coal

WebIn general, pencil graphite is not reactive enough to microwaves. So, a thin oil is used to concentrate the heat in a specific area of the graphite. Also, as the oil heats up and begins to burn, it chemically separates the binder in the pencil lead from the graphite. Place a few drops of olive oil onto a plate and lay the thread in the oil. WebGraphite may also be found in organic-rich shale's and coal beds. What makes graphite useful? Because it is a solid material, it is known as a dry lubricant. This is useful in applications where “wet” lubricants, such as oil, cannot be used. Graphite is the only non-metal element that is a good conductor of electricity. ...
