Preparation of High‐Purity Vitreous B₂S₃

Abstract

Preparation schemes for high-purity vitreous BzS3 (v-B2S3) with a S:B ratio of 1.478 k 0.032 are described. Preparation schemes reported in the literature are shown by very sensitive FT-IR measurements to yield v-BZS3 with significant oxygen contamination. Through extreme care taken in carbonizing silica reaction tubes and through the use of very high purity starting materials, oxygen contamination of less than 1% has been achieved. The IR spectrum for very pure v-BZS3 contains only two absorption bands. [

Preparation and characterization of new proton conducting chalcogenide glasses

“…First, glassy boron sulfide v-B 2 S 3 , was prepared by reacting the elements in a carbon coated and sealed silica tube [5]. Finely powdered v-B 2 S 3 was placed in a carbon crucible and heated to about 500°C in a long vertical silica reactor [6].…”

Structure and properties of lithium thio-boro-germanate glasses

“…Cho et al [4,15] showed in the binary Li 2 S + B 2 S 3 glasses through chemical analysis that bands of similar intensity in the 1000-1500 cm À1 range constituted less than 1 wt% of the sample and for this were ignored. The addition of LiI to the x ¼ 0:55 Li 2 S sample some narrowing of the peaks occur, but otherwise it does not appear to significantly alter the structural features seen in the IR spectra.…”

Structure determination of low-alkali-content Na2S+B2S3 glasses using neutron and synchrotron X-ray diffraction

“…As a strong glass-forming material, boron trisulfide (B 2 S 3 ) makes an excellent network glass former [1]. Recent interest in thioborate and related chalcogenide glasses is due to their fast ion conducting (FIC) behavior when suitably doped with alkali sulfide (M 2 S) modifier and considered as solid state electrolytes in solid state batteries [2,3].…”
