© Published under licence by IOP Publishing Ltd.High-density ceramic based on silicon carbide with the addition of beryllium oxide compositions (1-2)% wt. With a step of 0.2 was obtained. X-ray diffraction studies of SiC-BeO ceramics showed changes in the lattice parameter of SiC "c"with the addition of beryllium oxide, the minimum value of which was observed for a composition of 1.4% wt. BeO. For compositions greater than 1.4% wt. BeO was observed only polytype 6H. The grain size of sintered ceramic materials reached up to 20 microns. The elastic moduli, microhardness, and shear strength for hot-pressed SiC-BeO ceramic materials are determined.
