· JVASP-91480· K3Sb7S3O9

K3Sb7S3O9 is an oxysulfide ceramic compound containing potassium, antimony, sulfur, and oxygen—a mixed-anion ceramic that combines ionic and covalent bonding characteristics. This is a research-phase material that has not yet established widespread industrial use; compounds in this antimony oxysulfide family are primarily of academic interest for their potential in solid-state chemistry, photocatalysis, and ion-conducting applications. Engineers would consider this material only in exploratory projects targeting niche applications in energy storage, optical materials, or environmental remediation where the unique combination of oxides and sulfides might offer advantages over conventional alternatives.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
