The microstructure of 13 samples was investigated. Of these, 2 powder and 11 dense materials. On samples 1, 2, 3, 4, 5, 6, Washer 2 failed to identify the size of the grains, since the grain boundaries did not manifest. It is recommended to conduct additional operations of thermal and / or chemical etching to identify the grain boundaries. As a result of the investigation of the microstructure of samples 103-10 min, 104-25 min, MgF2, MgF2-39, the distribution of grains for Investigations were conducted on the size: 1-4 microns, 1-5 microns, <1 microns and 2-4 microns, respectively.
