In situ high‐temperature X‐ray diffraction study of the Rb₂O‐B₂O₃ glass forming system

Abstract

The results of X-ray structural analysis, in situ powder high temperature X-ray diffraction (HTXRD), DTA and annealing studies are summarized to refine the phase equilibria in the Rb 2 O-B 2 O 3 system in air. Samples were prepared by solid state reaction as well as by the crystallisation of glasses. Investigations show that, in the latter case, high-temperature metastable phases crystallise first, and it takes some months to reach phase equilibria.

“…All samples were made following traditional high-temperature melting and heat treatment method based on previous studies, which is commonly used to prepare QDs [ 32 , 33 ]. TeO 2 (99.99 %, Aladdin), Al 2 O 3 (99.999 %, Aladdin), H 3 BO 3 (99.99 %, Aladdin), ZnO (99.99 %, Aladdin), Na 2 CO 3 (99.99 %, Aladdin), CaF 2 (Analytically pure, Tianjin Zhiyuan Chemical), ErF 3 (99.9 %, Aladdin), CsBr (99.999 %, Aladdin) and PbBr 2 (99 %, Aladdin) were used as purchased without further purification.…”
