Abstract
The present invention provides a low density and porous zirconia (ZrO) powder partially alloyed with one or more of yttria, scandia, dysprosia, ytterbia, or any of the oxides of lanthanide or actinide. The total amount of alloying oxides should be less than about 30 weight percent. The powder is manufactured by controlled sintering or light plasma densification of physically agglomerated, or chemically derived zirconia composite powder that contains proper amounts of yttria, scandia, dysprosia, ytterbia, or any of the oxides of lanthanide or actinide, or any combination of the aforementioned oxides. The resulting coating from use of the inventive powder has a monoclinic phase content of less than 5 percent.
