Synthetic Hydrogen-containing Ultramarine Phases

Hydrogen was analyzed on synthetic sulfur-containing sodalite-type sodium aluminosilicates. Specimens synthesized from the NaAlSiO4-Na2S system in a H2 or N2 atomsphere or in a N2-S2 atmosphere contained hydrogens which were introduced by ion-exchange during water-washing. Specimens synthesized from...

Summary:Hydrogen was analyzed on synthetic sulfur-containing sodalite-type sodium aluminosilicates. Specimens synthesized from the NaAlSiO4-Na2S system in a H2 or N2 atomsphere or in a N2-S2 atmosphere contained hydrogens which were introduced by ion-exchange during water-washing. Specimens synthesized from the same system in H2S-containing atmospheres also contained hydrogens introduced from the synthetic atmosphere. The latter specimens had the formula: Na8Al6-Si6O24S·xH2S·yS, which was characterized by a constant number of sodium ions (eight per unit cell), whereas the former contained variable numbers of sodium ions according to the duration of water-washing. A difference in correlation between the sulfur content and the lattice constant was observed between these two series of specimens, indicating different manners of existence of the hydrogen.
