Thermal barrier coating made from a thermally sprayable powder that includes yttria stabilized zirconia and hafnia, from 6 to 9 weight percent yttria, and total impurities less than or equal to about 0.1 weight percent. The thermal barrier coating has from about 5 to 250 vertical macro cracks per 25.4 mm length measured along a coating surface and the macro cracks are oriented perpendicular to a surface of a substrate containing said coating.
