Graphitization degree

Graphitization degree
The "graphitization" process in which amorphous carbon is converted into graphite is an amorphous to crystalline conversion process, and the calculation of crystallinity is expressed by the so-called "graphitization degree". The degree of graphitization is the degree to which the carbon atoms form a close-packed hexagonal graphite crystal structure. The closer the lattice size is to the point constant of the ideal graphite, the higher the degree of graphitization.


Mix the graphite C to be sampled with the Si standard sample and perform XRD measurement;
