ZrO2 56Y2O3 Powder Description:
ZrO2 56Y2O3 Powder is a high-yttria yttrium-stabilized zirconium oxide produced through agglomeration and plasma densification. It is designed to significantly enhance the performance of thermal barrier coatings (TBCs) by improving resistance to CMAS (Calcium Magnesia Alumina Silicate) degradation at temperatures exceeding 1250°C (2280°F). Coatings made with ZrO2 56Y2O3 Powder offer excellent high-temperature stability, reduced thermal conductivity compared to conventional 7-8 wt.% yttria-stabilized zirconia (YSZ), and superior thermal shock resistance when applied as a topcoat over standard YSZ TBC systems. These coatings also have a thermal expansion coefficient similar to traditional TBC systems and can be effectively applied using atmospheric plasma spray methods.
