Many structural parameters have been proposed to discuss the structure of carbon. Among them, the lattice constant, crystallite size, and degree of graphitization are important parameters. The evaluation method of these parameters has been improved with the evolution of the X-ray diffraction measurement method, the numerical analysis method, and computer analysis. This paper first introduces the classical theory of carbon X-ray diffraction measurement, and then details how to embody the classical theory with high accuracy on current computers for beginners in the field of carbon research.
