K2Zn3S4
ceramic· JVASP-121434· K2Zn3S4
K2Zn3S4 is a ternary sulfide ceramic compound belonging to the thiospinel family, combining potassium, zinc, and sulfur in a crystalline structure. This material is primarily of research interest for optoelectronic and photocatalytic applications, where its sulfide-based composition offers band gap properties suited to visible-light absorption and semiconductor device development. While not yet established in mainstream industrial production, materials in this thiospinel class are being investigated for photocatalysis, solid-state lighting, and next-generation solar conversion technologies where conventional oxides are insufficient.

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.
