A refractory object may include a zircon body that is intentionally doped with a dopant including an alkaline earth element and aluminum. The refractory object can have an improved creep deformation rate. In an embodiment, the refractory object can have a creep deformation rate of not greater than about 1.8 E-5 hat a temperature of 1350&#xb0; C. and a stress of 2 MPa. In another embodiment, the zircon body may include an amorphous phase including an alkaline earth metal element.

Refractory object and method of forming

An electrode can include a functional layer having an LnMOphase, where Ln is at least one lanthanide optionally doped with a metal and M is at least one 3d transition metal, and a heavily-doped ceria phase. In an embodiment, the ceria phase can be present in the functional layer in an amount of at least 40 vol % based on a total volume of the functional layer absent any porosity. An electrochemical device or a sensor device can include the electrode.
