FIELD: chemistry.
SUBSTANCE: invention relates to production of boron suboxide composite material which can be used as an abrasive. The composite material contains crushed or granulated boron suboxide, AlxByOz distributed in a binding phase, where x ranges from 4 to 8, y ranges from 2 to 4 and z ranges from 9 to 33. The amount of the binding phase is less than 30% of the mass of the composite material, preferably 3-15 wt %. In order to obtain the composite material, a coating of aluminium or aluminium compound is applied on the boron suboxide particles and then sintered at temperature higher than 1600°C and pressure lower than 300 MPa.
EFFECT: high impact viscosity of the material.
