Abstract
The free liquid phase sintering method was applied to obtain the dense (relative density 99,5 %) materials based on silicon carbide. The eutectic mixture of MgO, Y2O3 and Al2O3 of the composition corresponding to the garnet ‒ spinele coexisting phase curve was used as the sintering agent. When preparing the burden powders the method was used of the chemical deposition out of the salt's solutions, the salts further creating the eutectic composition oxides spacing uniformly above the silicon carbide powder particles. The materials produced have elevated mechanical properties: elastic strain energy 410 GPa, bending strength 680 MPa, КIc = 6,0 МПа·м1/2, HV 21,5 ГПа, which values are close to the corresponding indexes for the hot-pressed carbide-silicon materials.
