What Is Yttrium Oxide Ceramic?
Yttrium oxide ceramic (Y₂O₃) is a type of advanced oxide ceramic made by shaping and sintering high-purity yttrium oxide into stable solid components. It is widely recognized in industrial and research fields for its role in producing yttrium oxide ceramic crucibles, Y₂O₃ transparent ceramic parts, sputtering target blanks, and other engineered ceramic structures.
Yttrium Oxide Ceramic (Y₂O₃) Advantages
Y₂O₃ ceramic remains stable when exposed to titanium, TiAl alloys, and vapor-phase environments, helping users maintain alloy purity, minimize process interruptions, and keep melting or coating systems running consistently without unexpected material reactions.
Although Y₂O₃ is a premium ceramic, its process compatibility and predictable behavior reduce part replacements, equipment downtime, and scrap losses—providing a more controlled cost structure for production and R&D operations.
Yttrium oxide ceramic interacts minimally with reactive metals and specialty coatings, helping users achieve cleaner alloy compositions, smoother coating layers, and higher repeatability in precision optical or PVD applications.
Y₂O₃ ceramics can be produced as crucibles, windows, liners, shields, and sputtering-target blanks in custom shapes, step features, precise tolerances, and surfaces suited to furnace, coating, or optical system designs.
Properties of Yttrium Oxide Ceramics
Yttrium oxide ceramic (Y₂O₃) offers high thermal stability, strong chemical inertness, and excellent compatibility with reactive metals such as titanium and TiAl alloys. Its clean processing behavior, corrosion resistance, and stable dielectric performance make it suitable for high-temperature melting, vacuum environments, thin-film coating systems, and advanced optical applications.
