| Abstract: | On the Preparation and Constitution of the Compound 3 CaO · 3 GeO2 · H2O In the temperature range from 100–∽450°C it is possible to prepare under hydrothermal conditions from equimolar mixtures of CaO and GeO2 the compound 3 CaGeO3 · H2O. By n.m.r. measurements of the solid compound it is shown, that there are only OH groups and no molecular water. It seems to be probable that this compound is a trigermanate of the formula Ca3H2 [Ge3O10]. |
