· K4 Sc2 Si8 O20 F2

K4Sc2Si8O20F2 is a fluorosilicate ceramic compound containing potassium, scandium, silicon, oxygen, and fluorine. This is a research-phase material likely studied for its potential as a refractory or functional ceramic, belonging to the broader family of complex silicate frameworks that can offer thermal stability and chemical resistance. Such scandium-bearing silicates are of interest in high-temperature applications and advanced ceramic research, though this particular composition appears to be in early-stage investigation rather than established industrial production.
