COMPOSITION AND SPECTROSCOPIC STUDIES OF HYDRATED SODIUM ALUMINATE COMPOUNDS |
|
| Abstract: | XRD, IR, NMR and a "tracer method" are used to investigate two hydrated sodium aluminates. It has been found that the compositions of these two compounds are 4Na2O-Al2O-3-12H2O and Na2O-Al2O3-2.5H2O, respecttvely. The aluminate anion in the former consists of condensed AlO4 tetrahedra. |
| Keywords: | sodium aluminate hydrate composition spectroscopic study |
