Relative density is with respect to primary particle density and equals (1 — e) where e is the solid volume fraction.

Direct interrelation between the properties of the initial aluminium hydroxides and structural-mechanical properties of the final alumina granules was established. Preparation of fibrous pseudoboehmlte in mild precipitation conditions allows to prepare from it the fine porous strong alumina granules. Formation of pseudoboehmlte in the form of well crystallized needles and plates unable to react with acid-peptizator requires the introduction of the intensive grinding into the technological process.
