· JVASP-28388· B2S2O9

B₂S₂O₉ is an oxysulfide ceramic compound combining boron, sulfur, and oxygen in a mixed-valence crystal structure. This material belongs to the family of borate-sulfate ceramics, which remain largely in the research phase but show promise for applications requiring thermally stable, chemically resistant ceramic phases. The compound's layered structural characteristics and moderate density make it of interest for exploratory work in advanced ceramics, though industrial adoption remains limited and specific engineering applications are still being investigated within materials research communities.
