| Description
| - Easily filtrated alumina-oxides spherical precursors were prepared by homogeneous precipitation from aluminium(III) sulphate with urea. Urea was employed as precipitation agent. X-Ray powder diffraction (XRD) spectra identified three different phases, namely: alpha-boehmite, boehmite and hydrobasaluminite. The morphology of prepared samples was observing by SEM (scanning electron microscopy) equipped with EDX (energy dispersive analysis by X-rays). The spherical clusters were examined at small concentration and the hydrobasaluminite islands were observed at the largest concentration of reagents. The microstructure characteristics were obtained by BET (Brunauer-Emmett-Teller) and BJH (Barrel-Joyner-Halanda) methods. BET in wide range from 6 to 142 m(2)/g and the all kinds of porous distribution were acquired, respectively. These methods showed that relationship between phase structures and microstructure exists.

- Snadno filtrovatelné sférické prekurzory oxidu hliníku byli připraveny homogenním srážením Al2(SO4)3 s močovinou ve vodném prostředí. Močovina se využívá jako precipitační činidlo. Produkt byl charakterizován práškovou rtg. difrakcí. Byly získané tři následující fáze: alfa-boehmite, boehmite and hydrobasaluminite. Morfologie byla pozorována pomocí skenovacího elektronového mikroskopu. Mikrostrukturní charakteristiky byly získány metodami BET a BJH. S rostoucím obsahem koncentrace reakčních látek se měnily nejenom fáze, ale také docházelo ke zvyšování iregularity morfologie. U alfa-boehmitu byly objeveny makropóry. V boehmitu byly objeveny mezopóry s makropóry a u hydrobasaluminitu byly všechny tři druhy pórů na stejné úrovni. (cs)
