To improve the safety of handling and storing complex metal hydrides on board of automobiles, complex hydrides encapsulation in hollow glass microspheres was proposed and researched.
Formation of intact hollow glass microspheres with an open through wall porosity following phase separation and acid leaching of the boron oxide rich phase was demonstrated.
Encapsulation of sodium alanate within the prepared microspheres by diffusion through wall porosity was illustrated. The observation of unusual alanate structures in the form of needle bundles on the interior and exterior surfaces of the spheres following the encapsulation was obtained.
