ActivePitch products of coal carbonization—Determination of mesophase content—Microscopical analysis by reflected light
焦化沥青类产品 中间相含量的测定 光反射显微分析方法
Application Summary AI generated
This standard specifies a reflected light microscopy method for determining the mesophase content in pitch products derived from coal carbonization. It is applied in the chemical and coking industries to assess the quality and thermal transformation degree of coal tar pitch, particularly for materials used in carbon electrode manufacturing and advanced carbon materials production. The method enables quantitative evaluation of the optically anisotropic mesophase spheres, which directly correlates with the pitch's suitability for graphitization processes.
