· JVASP-44540· KHfPCO7

KHfPCO7 is a hafnium-based phosphate ceramic compound with a complex oxyphosphate structure, belonging to the family of refractory phosphate ceramics. This material is primarily of research interest for high-temperature applications where thermal stability and chemical inertness are critical, particularly in environments requiring resistance to corrosive molten salts or extreme thermal cycling. The hafnium component provides enhanced refractory performance compared to conventional phosphate ceramics, making it relevant for specialized thermal management and protective coating systems in aerospace and nuclear contexts.
