· K2NiF4

K2NiF4 is an inorganic fluoride compound belonging to the layered perovskite family, combining potassium, nickel, and fluorine in a crystalline structure. This material is primarily investigated in research contexts for solid-state ionics and advanced ceramics applications, particularly as a potential fluoride ion conductor for electrolyte membranes and energy storage systems. Its layered structure and ionic mobility make it of interest for next-generation solid-state batteries and fuel cells, where engineers seek alternatives to conventional electrolyte materials with improved thermal stability and ion transport properties.

Export Control

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.
