Zusammenfassung:FIELD: chemistry. ^ SUBSTANCE: invention concerns obtaining powder material of transitional aluminium oxide. First version involves powder material with inoculation particles of transitional aluminium oxide with form factor 3:1 or more and average particle size approximately over 110 nm and under 1000 nm. Second version involves powder material with needle-shaped inoculation particles containing transitional aluminium oxide, with form factor 3:1 or more, secondary form factor 3:1 or less, and average particle size approximately over 75 nm. Third version involves powder material with plate-shaped inoculation particles containing transitional aluminium oxide, with form factor 3:1 or more, secondary form factor 3:1 or more, and average particle size approximately over 125 nm. Method of obtaining involves use of aluminium metahydroxide precursor and aluminium metahydroxide inoculation in suspension, thermal processing of suspension to transform aluminium metahydroxide precursor into aluminium metahydroxide powder material at temperature over 120°C, and burning. ^ EFFECT: production of aluminium oxide powder with novel morphological properties. ^ 60 cl, 3 dwg, 3 ex
