METHOD OF OBTAINING CARBON NANOSTRUCTURES FRON ORGANIC COMPOUND AND METAL-CONTAINING SUBSTANCES Russian patent published in 2008 - IPC C01B31/02 B82B3/00 

FIELD: chemistry.

SUBSTANCE: as metal-containing substance wastes of non-ferrous metallurgy production is used - metallurgical dust, obtained as result of roasting of magnetic fractions and nickel concentrate, containing oxides of cobalt, nickel, copper, sulfides of nickel and copper. In presence of water mixture of metallurgical dust and polyvinyl alcohol (PVA) is prepared in ratio 1 mole of NiO contained in metallurgical dust per 1-4 moles of PVA. 5-10% PVA solution or dry PVA, which is crushed together with metallurgical dust with addition of minimal water amount for moistening and "connecting" components, can be used. Obtained mixture is dried on glass padding at 50°C, after which thermal processing with step-by-step heating to 400°C is carried out. Tubular, fused, sphere-shaped nanostructures are obtained, which can be hollow or filled with metals and their compounds: Ni, Cu, CoO, NiO, Cu₂O are obtained.

EFFECT: reduction of energy consumption and cost of target product; use of cheap raw material and metallurgical production wastes.
