Heading: Science for ceramic production

A composite based on polycrystalline cubic boron nitride with a refractory binder, characterized by a high degree of phase distribution homogeneity, was obtained by thermobaric treatment in a cubic press at a pressure of 6.0 GPa and a temperature of 1450 ° C. The homogeneity of the microstructure of the large-sized composite was confirmed by XRD, SEM, and XMA. Mechanical tests, impact turning tests of hardened steel, proved the high strength of the composite. Thus, composites made using this technology can be recommended for use in the mining industry.
