ZrO2 7.5Y2O3 Powder Description:
ZrO2 7.5Y2O3 Powder is a fused and crushed 7.5 wt.% yttria-stabilized zirconia (7.5Y2O3 ZrO2) designed for thermal barrier applications using atmospheric plasma spray technology. Unlike conventional 7-8% YSZ powders, this material features homogenous particle chemistry and higher density, resulting in sprayed 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 creates dense, segmented microstructures with excellent strain tolerance at high temperatures, making it ideal for gas turbine engine operations. Coatings applied via cascading arc gun technology (SinplexPro) benefit from improved process reliability and reduced application costs, suitable for industrial gas turbine and aerospace engine components.
