· JVASP-22929· Y2TiO5

Y2TiO5 (yttrium titanate) is an advanced ceramic compound belonging to the family of rare-earth titanates, which are inorganic, crystalline materials valued for their thermal and mechanical stability. This material is primarily of research and specialized industrial interest, used in high-temperature applications and as a thermal barrier coating constituent, particularly in aerospace and power generation sectors where thermal protection and chemical resistance are critical. Y2TiO5 is notable for its potential as an alternative or complementary phase in thermal barrier coating systems, offering advantages in thermal stability and resistance to sintering compared to conventional yttria-stabilized zirconia, making it relevant for engineers designing ultra-high-temperature structural components.
