UDC 666.3-13  Oxides, solutions of salts on the surface of silicon carbide

By liquid-phase sintering to obtain a dense materials based on carbide kremniya.V as sintering additive used oxides, Al2O3, Y2O3 and MgO, corresponding to the composition of yttrium aluminum garnet and triple eutectic point on the line of binary sections of garnet-spinel. Oxides deposited on the surface of the SiC powder by coprecipitation from salt solutions. The maximum density (rotn = 99.5%) was achieved in LPSSiC-material comprising 20 wt. % Sintering aids at 1800 ° C. Keywords coprecipitation from salt solutions, liquid phase sintering of silicon carbide, yttrium aluminum garnet, microstructure.

UDC 666.7; 66.041.3-65: 691.365  Possibility of increasing K.P.D.ENERGY kiln vermiculite concentrate, use the "hidden" exergy swells MATERIAL

The article assesses the efficiency of the process furnaces for burning the vermiculite with an additional non-electrified ("zero") module. Due to the low temperature in the electrical firing vermiculite modules included in the "zero" in the unfinished unit of heat absorption. Here they accumulated thermal exergy by conductive and radiative transfer in part, it goes into the deeper layers of the grain and the processes of heat absorption, dehydration and swelling of vermiculite completed. The effect is achieved by the introduction of "zero" of the module. Theoretically justified energy efficiency of new modification of the electrical module and triggers kilns. Key words: vermiculite, heat absorption, exergy, modular electric oven trigger module firing electrified modul>.
