Metastable phases in the MgO-Al//2O//3-H//2O system below 200 degree C have been studied. Mixtures of alumina gel and MgO were used as starting materials and submitted to hydrothermal treatment at different temperatures. Extensive solid solutions of Mg-doped gibbsite, Mg-doped boehmite and Al-doped brucite have been obtained.
