Preparation of high-purity vitreous B#72S#73
Preparation schemes for (#8n-B#72S#73) with a S:B ratio of 1.478#880.032 are described. Extreme care taken in carbonizing SiO#72 reaction tubes and use of very high purity starting materials results in O contamination of A1%. The ir spectrum for very pure n-B#72S#73 contains only two absorption band...
