Abstract
Pure samples of (NH4)(2)V6O16 were prepared by hydrothermal crystalliz ation of amorphous ammonium vanadate hydrate in the presence of LiOH s olution. By changing the conditions of the hydrothermal treatment, cry stallites differing by one order in size resulted. The ammonium hexava nadate thus prepared was thermally investigated by simultaneous TG and DTA, as a function of heating rate under a constant stream of differe nt gases.
