Preparation schemes for high‐purity vitreous B 2 S 3 ( v ‐B 2 S 3 ) with a S:B ratio of 1.478 ± 0.032 are described. Preparation schemes reported in the literature are shown by very sensitive FT‐IR measurements to yield v ‐B 2 S 3 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 ‐B 2 S 3 contains only two absorption bands.
