ZrO2 56Y2O3 Powder Description:
ZrO2 56Y2O3 Powder is a high-yttria yttrium-stabilized zirconium oxide, manufactured through agglomeration and plasma densification. This powder is engineered to greatly enhance the performance of thermal barrier coatings (TBCs) by improving their resistance to CMAS (Calcium Magnesium Aluminosilicate) degradation at temperatures above 1250°C (2280°F).
Coatings made with ZrO2 56Y2O3 Powder provide excellent high-temperature stability, reduced thermal conductivity compared to conventional 7-8 wt.% yttria-stabilized zirconia (YSZ), and superior thermal shock resistance when used as a topcoat over standard YSZ TBC systems. Additionally, these coatings maintain a thermal expansion coefficient similar to traditional TBC systems and can be effectively applied using atmospheric plasma spray techniques.
