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;

Calculate the 2θ diffraction angle values of graphite C (002 plane) and standard sample Si (111 plane) by fitting;

Calculate the degree of graphitization based on the graphite C (002 plane) or C (004 plane) 2θ value.
