The results of the raw corundum pellets drying condition investigation confrmed completely the supposition that the alumina-polystyrene-foam mixtures have the low sensitivity to the drying conditions. This fact allowed to combine the drying and the fring in one thermal vessel. As the vigorous evolution of the hydrolysis products and the polystyrene foam burning can damage the raw pellets, the heating rate should be set so that to give the gaseous products time to diffuse out of the material without breaching its structure. The well-targeted fring scheduler is proposed in the article.Ill.5.
Graphene/silica nanocomposites in the form of highly porous aerogels are obtained for the first time by integrating a novel approach for the production of low defectivity graphene with a two-step route for the synthesis of a silica-based monolith.
Fractional composition of the corundum pellets is defined mostly by the polystyrene foam balls grading, by the mixture moisture, and by the granulation's parameters. The using of the high dynamic packing loading influences negatively on the production quality. The plate' rotation frequency, its angle and the granulation time were established in the article. The conditions of the hollow pellets production on base of the technical alumina were developed.
