ZR5971 ZrO2 48Y2O3 Powder

ZrO2 48Y2O3 Powder Description:

ZrO2 48Y2O3 Powder is a high-yttria zirconia material, containing 48 wt.% yttria, specifically engineered for top coats in thermal barrier coatings (TBCs). This powder is designed to produce dense or segmented microstructures when applied using atmospheric plasma spray technology, offering significant advantages over conventional 7-8 wt.% yttria-stabilized zirconia. Its high yttria content ensures low thermal conductivity and excellent phase stability at elevated temperatures, which extends the service life of the coating. Additionally, ZrO2 48Y2O3 Powder provides enhanced resistance to molten sand and ash (CMAS), though it may have lower erosion resistance compared to lower yttria materials. The powder's fused and crushed manufacturing method results in coatings with very low porosity, making it suitable for use as a top coat in combination with intermediate layers of 7-8 wt.% yttria-stabilized zirconia and MCrAlY bond coats in multi-layer or graded TBC systems for industrial gas turbines and aerospace engines.
