FIELD: metallurgy.
SUBSTANCE: particles porosity is 60-80%, and porous structure is presented by long, parallel channels with close packing, with channels cross-section size 0.3-1.0 mcm and length up to 50 mcm.
EFFECT: structure of suggested aluminium oxide simplifies passage of the substances participating in various processes inside the particle ensuring access to the internal surface of the aluminium oxide, where both catalytic reactions and adsorption can occur.
