Yttrium oxide

Y₂O₃ for ceramics, electronics and coating systems
Yttrium oxide (Y₂O₃) is a white rare earth oxide that is stable at high temperatures. Due to its excellent thermal, chemical and dielectric properties, it is an indispensable material in the production of technical ceramics, in protective coatings and as a component of phosphors and laser materials. PROJECTOR supplies yttrium oxide in various qualities - from technical standard to high-purity research quality.

Frequently asked questions about yttrium oxide
Is yttrium oxide used as a stabilizer in zirconium oxide?
Yes. Yttrium oxide is the standard stabilizer for zirconium oxide (YSZ) in high-performance ceramics, for example for dental materials or fuel cells.
What form does PROJECTOR provide?
We supply yttrium oxide as a powder in technical or high-purity quality, also sieved or granulated on request – suitable for your process.
Can yttrium oxide be used in lasers?
Yes. Yttrium oxide-based crystals such as YAG or YVO₄ are frequently used in solid-state laser technology. PROJECTOR supplies the corresponding oxides for crystal synthesis.
