METHOD FOR OBTAINING AMORPHOUS MESOPOROUS AEROGEL OF ALUMINIUM HYDROXIDE WITH LAMINATED FIBROUS ORIENTED NANOSTRUCTURE

摘要

FIELD: metallurgy.SUBSTANCE: invention relates to methods for obtaining amorphous mesoporous aluminium hydroxide with a laminated fibrous microstructure. A method for obtaining amorphous mesoporous aerogel of aluminium hydroxide with a laminated fibrous oriented nanostructure involves the performance of a synthesis reaction of aluminium hydroxide aerogel in a tight container by the treatment of a binary melt with a steam-gas flow based on a mixture of inert and (or) low-active gases with a water vapour at the melt temperature of 280-1000°C. As the binary melt, bismuth with the aluminium content of 0.05-7.00 wt % is used.EFFECT: invention allows improving technical and economic indices at the production of nanostructured aerogel AlOOH.1 dwg, 1 tbl
