Phase formation upon crystallization of SrO · 2B2O3 glasses

The crystallization of SrO · 2B 2 O 3 glasses has been studied. Four different crystalline formations were found to form simultaneously and independently on the glass surface: stable α-SrB 4 O 7 crystals and metastable crystalline forms (β-SrB 4 O 7 , Sr 4 B 14 O 25 , and spherulites (presumably, mi...

Description
Summary:The crystallization of SrO · 2B 2 O 3 glasses has been studied. Four different crystalline formations were found to form simultaneously and independently on the glass surface: stable α-SrB 4 O 7 crystals and metastable crystalline forms (β-SrB 4 O 7 , Sr 4 B 14 O 25 , and spherulites (presumably, mixtures of crystalline phases)). The ranges of thermal stability of the newly formed metastable phases have been established using thermal analysis.
