FIELD: chemistry.
SUBSTANCE: thermal processing of tested samples in carried out in vacuum or inert gas with further analysis, in which a degree of conversion of diamond-like forms of boron nitride into a graphite-like phase with a hexagonal structure is determined and used to assess a value of the product heat resistance, with the samples being crushed to a fraction size value of 100÷500 mcm before thermal processing and carrying out the sample analysis by an X-ray phase method.
EFFECT: providing a possibility of obtaining a reliable result of the product heat resistance.
