Description	Dysprosia-stabilized zirconia (DySZ) is a promising candidate to replace yttria-stabilized zirconia(YSZ)as a thermal barrier coating due to its lower inherent thermal conductivity.It is also suggested in studies that DySZ may show greater stability to high temperature phase changes compared to YSZ, possibly allowing for coatings with extended lifetimes.Separately,the impurity content of YSZ powders has been proven to influence high-temperature sintering behavior.By lowering the impurity oxides within the spray powder,a coating more resistant to sintering can be produced.This study presents both high purity and standard purity dysprosia and YSZ coatings and their performance after a long heat treatment.Coatings were produced using powder with the same morphology and grain size;only the dopant and impurity content were varied. Samples have been heat treated for exposure times up to 400 h at a temperature of 1150 °C. Samples were measured for thermal conductivity to plot the evolution Dysprosia-stabilized zirconia (DySZ) is a promising candidate to replace yttria-stabilized zirconia(YSZ)as a thermal barrier coating due to its lower inherent thermal conductivity.It is also suggested in studies that DySZ may show greater stability to high temperature phase changes compared to YSZ, possibly allowing for coatings with extended lifetimes.Separately,the impurity content of YSZ powders has been proven to influence high-temperature sintering behavior.By lowering the impurity oxides within the spray powder,a coating more resistant to sintering can be produced.This study presents both high purity and standard purity dysprosia and YSZ coatings and their performance after a long heat treatment.Coatings were produced using powder with the same morphology and grain size;only the dopant and impurity content were varied.
