<p>The purity, quality and structure of hexagonal boron nitride (h-BN), an industrial product, were analyzed by numerical model using optical scattering method. Light intensity distributions were calculated with the help of known optical parameters and the cylindrical model developed for h-BN. In the crystal structure of h-HB considered as a microcylindrical container, light scattering was calculated according to the incident light intensity and dielectric parameters for the material with different absorbance values ​​and distribution curves were obtained. The standard model was obtained from the light intensity data calculated for different absorbing and non-absorbing environments in the cylindrical model designed for numerical calculations. As an important industrial product, it was observed that the numerical calculation results and physical structure descriptions obtained for the h-BN standard model, alargely coincide with the results of previous studies using similar methods applied to different materials.</p>
