Kol'tsova Y. Glass-ceramic materials of tribotechnical function on the basis of silicon carbide

The possibility of usage different systems glasses for liquidphase sintering of silicon carbide was established, and optimal proportion of "silicon carbide - glass" mixture was obtained; the compositions of technological compatible with silicon carbide by the base properties glass-bondes (in systems MgO-Al2O3-SiO2, MgO-CaO-Al2O3-SiO2, MgO-Al2O3-SiO2- ZrO2, MgO-CaO-Al2O3-SiO2-ZrO2) have been developed; the peculiarity of processes, which occured during the sintering of silicon carbide glass-ceramics were obtained; the influence of conditions and regimes of the "silicon carbide - glass" mixture grinding, antifriction additions and temperature - time regime of burning on the sintering and properties glass-ceramics was established. The silicon carbide glass-ceramic materials were industrial tested as seals, and the high exploitation characteristics were obtained.
