| Abstract |
| The present work aims at qualitative investigation of cesium content present in a
glass. A glass comprising (wt%) Cs2O(30)-SiO2(35)-Na2O(7)-SnO2(4)-ZnO(24) was
prepared in a conventional heating furnace. A novel method was developed adopting
gravimetric analysis of cesium content in the glass samples using Dragendorff’s
reagent, leading to formation of Cs3Bi2I9 crystal (salt). Experimental methods were
examined to purify the salt. Qualitative analysis was performed on Cs3Bi2I9 crystal
with FESEM-EDX and XRD. Up to ~93% pure Cs3Bi2I9 could be synthesized. Quantitative
studies were performed with standard cesium solution prepared with Cs2CO3 with
varying compositions of cesium within 1000 to 3000 ppm. Weight of salt produced
was concluded to be strongly related to the cesium content present in the glass
solution.
