Graphite tailings were used as the raw materials for preparation of foamed ceramics via a high-temperature self-foaming method. The residual carbon in acted foaming agent and no additional agents required. reacted with Fe2O3 produced gas that was wrapped by liquid phase to form porous structure. effects sintering temperature, holding time, content, flux on bulk density, water absorption, mean p...

The possibility of obtaining building foamed glass-ceramic using the diamond concentration tailings Lomonosov deposit in Arkhangelsk Region, Russia, is demonstrated here. effect tailings’ particle size distribution, feed temperature, addition a foaming agent, and content oxidizer on charge established. process conditions for materials are described. specifications with optimal composition (tail...
