· K1 Nb4 O5 F1

K1Nb4O5F1 is a mixed-valence niobium oxide-fluoride ceramic compound belonging to the family of layered perovskite-related oxyfluorides. This is a research-stage material studied primarily for its ion-conduction and photocatalytic properties rather than a commercially established engineering material. The material is of interest in electrochemical energy storage, photocatalysis, and solid-state ionics research, where the combination of niobium's redox activity and fluorine's electronegativity offers potential advantages in applications requiring selective ion transport or light-driven chemical processes.

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.
