Abstract
A study has been made of the effect of production conditions on chemical and phase composition, morphological structure, and surface area of aluminum and magnesium hydroxides synthesized in “equilibrium” and “nonequilibrium” conditions. Preliminary polycondensation in concentrated solutions of nitrate salts of aluminum and magnesium at different temperatures does not affect the properties of the resulting hydroxides substantially. The determining factors are the conditions of precipitation (pH, temperature and length of aging) and how pH is maintained (variable or constant). Conditions have been established for formation of pseudoboehmite with a particle size of ∿30 Å, isotropic in all directions, of an amorphous aluminum hydroxide with different composition, and of magnesium hydroxide with particular morphological structures (needles and plates) and surface area.
