ZR5967 Zirconium Dioxide Yttrium Oxide Composite Spherical Powder (ZrO2 56Y2O3 Powder)

ZrO2 56Y2O3 Powder Description:

ZrO2 56Y2O3 Powder is a yttrium-stabilised zirconium oxide produced through agglomeration and plasma densification. It is designed to significantly improve the performance of thermal barrier coatings (TBCs) by enhancing resistance to CMAS (Calcium-Magnesia-Alumina-Silicate) at temperatures exceeding 1 250°C (2 280°F). Coatings made from ZrO2 56Y2O3 Powder offer excellent high-temperature stability, lower thermal conductivity compared to conventional yttrium oxide-stabilised zirconium dioxide (YSZ) with 7-8 wt% and better thermal cycling resistance when applied as a top coat over standard YSZ TBC systems. These coatings also possess a thermal expansion coefficient similar to conventional TBC systems and can be effectively applied using atmospheric plasma spray processes.
