In this paper the contribution of heterocoagulation of silica sols on powder materials to the formation of nanostructured forms of silicon oxide is presented. To a greater extent heterocoagulation is more appeared on the advanced surfaces of refractory particles and clay, and to a lesser extent on the particles of alumina and silica oxide, the surfaces of which contained significantly fewer active centers. Silica sols have positive effect on drying and firing modes of ceramic materials. It was established that the application of silica sol as binder in the preparation of aluminum silicate ceramics allows to reduce the firing temperature to 150-200oC with a simultaneous increasing of strength characteristics.

“…These materials are of a particular interest as they are mechanically and chemically stable upon heating. Based on the principles of the sol-gel and SHS-technologies, there have been earlier synthesized the inorganic carbonaceous composites that have unique properties when they are used to line the induction furnaces [2,3]. From the scienti c point of view this synthesis can be carried out as one stage synthesis (direct synthesis) of the multicomponental ceramic materials consisting both of the single-phase compounds (e.g.…”

SHS - Processes in the Carbonaceous Oxide System at High Nitrogen Pressure Values

<p>This paper contains study results of the nitride containing composites features formed in the compacted Al-TiO<sub>2</sub>-C-Si samples inside a high pressure reactor with various nitrogen pressure values. The nitriding and carbide-formation processes take place simultaneously with aluminothermic reduction of titanium oxide in the self-propagating high-temperature synthesis (SHS) mode. It has been found that the nitrogen pressure effect is manifested as insignificant reduction of the combustion temperature and increased durability of the synthesized composite. The SHS process in the nitric environment leads to practically complete reduction of titanium oxide, the free titanium being absent. The X-ray analysis has revealed that the basic SHS products are refractory compounds such as metal nitrides, carbides, and oxides. Increase in nitrogen pressure results in decrease of the specific electric resistance of the synthesized composites caused by growth of the electroconductive phases i.e. titanium carbides, nitrides, and silicides. Performed electron microscopic study including the energy dispersion analysis of the morphology and structure of the SHS products has revealed formation of the nano-sized titanium silicide crystals distributed between the complex carbonitride particles. The complex carbonitride composites synthesized in the high pressure reactor are of interest as highrefractory and abrasive materials considering their physical and chemical properties.</p>
