The purpose of the research was to study the structure of MPG-7 fine-grained graphite by X-ray inspection and scanning electron microscope investigation methods. We carried out a structural and local chemical analysis of inhomogeneities occurring in graphite blanks. According to the data obtained, we changed technical documentation for the incoming quality control of MPG-7 graphite blanks and details.

By X-ray diffraction analysis and Raman spectroscopy, we studied samples of fine-grained graphite MPG-7 with detected chemical and structural defects. We determined the effect of structural and chemical defects on the micro- and macrostructure of graphite and estimated its crystallinity depending on the type of defects detected.

Rubbery heat-shielding coatings (RHSCs) are widely used in the aircraft industry and in rocket building. The chemical composition and processing methods of RHSCs are similar to those of general-purpose rubbers. However, the presence of special additives in their composition ensures increased heat resistance and thermal stability of articles. One of the important aspects of formation of a high-quality heat-shielding coating is the choice of anti-adhesive lubrication applied to the forming surface of the compression mould.
