  【Popularization of Science】The main performance characteristics and application of graphite

  2022-05-17

  The name graphite comes from the Greek word "graphein", which means "to write". Named in 1789 by German chemist and mineralogist A. G. Werner. Graphite is an allotrope of elemental carbon. Each carbon atom is surrounded by three other carbon atoms (multiple hexagons arranged in a honeycomb pattern) to form a covalent molecule. Graphite is a crystalline mineral of carbonaceous elements, and its cr
