The work is devoted to the production of iron oxide from industrial waste for its further use in the production of ceramics, catalysts and sorbents. It is proposed to use iron-containing waste from the ...
Silica adsorbents with organosilsesquioxane fragments containing organic radicals have been obtained for use in the adsorption separation of oxygen-argon mixtures by the PSA method. The sol-gel scheme ...
The paper investigates the possibility of thermal processing of waste from the chemical industry – phosphogypsum. It is shown that when phosphogypsum is dried, partial dehydration of dihydrous calcium ...
The article presents the results of determining the anti-filtration and sorption capacity of palygorskite and other clays of the Borshchevsky and Voskresensky cement raw material deposits, which are overburden ...
The volumes of large-tonnage mineral waste generation cause serious concern from the side of environmental supervision. Most of the mineral waste is a valuable secondary raw material, but the lack of integrated ...
The main directions of application of flexible heat insulating materials and traditional technologies for producing non-woven materials are considered. Various ways of fastening fibers are analyzed, such ...
The glass-crystalline ceramic materials in SiO2–Al2O3–RO (RO–MgO, SrO, BaO and their combinations) systems have been synthesized by the sol-gel method. The factors influencing on the sol-gel formation ...
