FIELD: technological processes.
SUBSTANCE: method of bone processing to produce hydroxyapatite is proposed. The method includes grinding and defatting of the bones and their heat treatment. Prior to the heat treatment, a furnace with an offtake pipe is heated up to a temperature of 700-1000°C and heat treatment at the given temperature is performed. The resulting pyrolysis gases are discharged through the offtake pipe and condensed. Grinding is done to obtain fragments with a thickness of 3-8 mm, and defatting is done in boiling water, with the addition of a carbonate salt and an organic acid.
EFFECT: invention makes it possible to carry out the process without the use of additional consumables, in one step, while maintaining the quality of the product obtained.
