It is difficult to imagine modem technology without small particles, 1-1000 nm in size, because virtually every industry depends in some way on the use of such materials. Catalysts, printing inks, paper, dyes and pigments, many medicinal products, ad

Hydroprocessing catalysts were prepared using fibrillar aluminas as carrier materials and sulphides of nickel and molybdenum as active substances. The fibrillar aluminas were obtained from fibrillar boehmite samples prepared at three different synthe

A procedure for coating alumina fibre bundles with fibrillar boehmite particles is described. Fibrillar boehmite particles, having a specific surface area of 150 m2/g, were adsorbed onto the surface of the alumina fibres. The surface of the alumina f

A method for preparing particles with highly dispersed ceria by a stepwise procedure is described. The surface of silica particles was modified by aluminate and coated with an interlayer of titanina. CeOSO4 was deposited on the titania coated silica
