K2InP2S7
ceramic· JVASP-42046· K2InP2S7
K2InP2S7 is a mixed-metal sulfide ceramic compound containing potassium, indium, and phosphorus in a sulfide lattice structure. This material belongs to the family of quaternary chalcogenide ceramics, which are primarily investigated for optoelectronic and photonic applications due to their wide bandgap and potential nonlinear optical properties. While still largely in the research phase rather than widespread industrial production, materials in this compound class show promise for mid-infrared photonics, solid-state laser systems, and sensing applications where conventional oxides or single-element semiconductors fall short.

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.
