Abstract
The porous blank samples of В4С + С and В4С + С + Si materials were impregnated by liquid silicon to obtain the high-dense product whose the relative density is equal to 99,0 %, and porosity equal to 0,9 %. The silicon impregnation was carried out by means of the sample saturation through the usable blank samples SiC + C. This method allows to reduce both the carbide grains dissipation in the silicon solution and the creation of the B12(C, Si, B)3 phase, this reduces the fragility of the product and thereby improving the mechanical characteristics of the B4C ceramics.
