Kulich V. Optimization of the structure parameters of the self-bounded silicon carbide of exchacced shock resistence

As a result of the carried out research optimum relationships of the coarse silicon carbide fractions to fine-dispersion ones (d1/d2 = 20) are defined and the relation of volume parts of powders fractions as 5:3 at which volume concentration of a mix of powders in the bricks formed by a method of a slip casting, attains a maximum (0, 76 volumes), and density of the self-bounded silicon carbide obtained from these bricks attains level 3,10…3,12 g/sm3. High-duty production technology of formation and sintering of plates from the self-bounded silicon carbide of the enhanced impact resistance in weight up to 50 kg is created. For the first time it is established, that magnitude of density of the self-bounded silicon carbide for shock- resistant elements should change within a range of values from 3,02 to 3,10 g/sm3 . Ceramic plates and shock-resistant blocks on their basis are created dynamic tests of which have confirmed their for application under conditions of dynamic strikers with the big kinetic energy (to 16 kJ) influence.
