Features of strontium tetraborate synthesis by means of borate rearrangement

The results of thermoanalytical and x-ray diffraction measurements show that strontium tetraborate (SrB 4 O 7 ) is formed as the result of crystallization of an amorphous substance at 750°C. The amorphous substance was obtained by dehydration of a mixture of strontium borate crystal hydrates synthes...

Summary:The results of thermoanalytical and x-ray diffraction measurements show that strontium tetraborate (SrB 4 O 7 ) is formed as the result of crystallization of an amorphous substance at 750°C. The amorphous substance was obtained by dehydration of a mixture of strontium borate crystal hydrates synthesized at 95 ± 5°C via solid-state interaction of orthoboric acid with strontium carbonate. Conditions for reproducible synthesis of single-phase SrB 4 O 7 by means of borate rearrangement have been established.
