Synthesis of mullite precursors in molten salts. Influence of the molten alkali nitrate and additives

Silica gel and aluminium salt, in the stoichiometric ratio for mullite (Al/Si=3), have been used to prepare the mullite precursor by reaction in molten alkali nitrates at 450°C. The influence of the nitrate (NaNO 3, KNO 3 or mixture NaNO 3–KNO 3) and the additives (Ca 2+, Ba 2+, Bi 3+) on the phase...
