What is the difference between natural graphite and artificial graphite? 

They come from different sources. Natural graphite is an ore formed in the Earth's crust and obtained after mining and processing. Artificial graphite is obtained by high temperature and high-pressure treatment of carbon materials (such as graphite ore, coke, etc.) or chemical synthesis.

The structure of natural graphite is composed of carbon atoms arranged into a layered crystal structure, while the structure of artificial graphite can be in various forms, such as block, fiber, or powder. This structural difference makes them different in physical and chemical properties.

There are also differences between natural graphite and artificial graphite in the field of application. Natural graphite is often used in batteries, lubricants, graphite electrodes, and other fields, while artificial graphite is widely used in electronics, aerospace, chemical, composite materials, and other fields.
