- Abstract
Thermal hydrolysis of aluminum chloride was studied using36Cl and3H tracers in combination with energy-dispersive and morphological (scanning electron microscopy) analyses. Pure partially hydrated AlCl3 or mixtures of AlCl3 and AlCl3 · 6H2O were used as initial materials. It was found that Al7O10Cl · 2H2O microtubes along with isometric microparticles are formed in the course of thermal hydrolysis due to evaporation and partial hydrolysis of the initial AlCl3. In this case, AlCl3 · 6H2O acts as a source of water vapor, whereas chlorine atoms contained in this compound do not pass into the microtube material. The tests with water labeled with tritium also showed no incorporation of tritium in microtubes. Thus, thermal hydrolysis of AlCl3 proceeds predominantly by the recrystallization mechanism.
