· Hf4 Ti4 O16

Hf4Ti4O16 is a mixed-metal oxide ceramic compound combining hafnium and titanium in a layered perovskite or pyrochlore-related crystal structure. This material is primarily investigated in materials research for high-temperature applications and as a thermal barrier coating component, leveraging the refractory properties of hafnium oxide combined with the mechanical stability and thermal conductivity characteristics of titanium oxide. Its mixed-cation design makes it a candidate for advanced aerospace and thermal management systems where conventional single-oxide ceramics reach performance limits.
