| 1. A thermal barrier coating, comprising:
a ceramic based compound selected from the group consisting of yttria stabilized zirconia, calcia stabilized zirconia, magnesia
stabilized zirconia, yttria stabilized hafnia, calcia stabilized hafnia and magnesia stabilized hafnia;
a metal oxide; and
a metal comprising a diameter of about 10 nanometers to about 1000 nanometers and present in an amount of at least about 25
percent by weight of said ceramic based compound,
wherein the thermal barrier coating comprises a porosity of no more than 20 percent by volume of said ceramic based compound.
