ZrO2 7.5Y2O3 Powder Description:
ZrO2 7.5Y2O3 Powder is a fused and crushed 7.5 wt.% yttria-stabilized zirconia (7.5Y2O3 ZrO2) specifically designed for thermal barrier applications using atmospheric plasma spray technology. Unlike conventional 7-8% YSZ powders, this material boasts homogenous particle chemistry and higher density, resulting in coatings with very low porosity, enhanced erosion resistance, and high inter-particle cohesion. Its high purity levels lead to improved sintering properties, producing white coatings.
ZrO2 7.5Y2O3 Powder forms dense, segmented microstructures with excellent strain tolerance at high temperatures, making it perfect for gas turbine engine operations. Coatings applied using cascading arc gun technology (SinplexPro) benefit from improved process reliability and reduced application costs, making them suitable for industrial gas turbine and aerospace engine components.
