    The high temperature ceramic alumina, (Al 2 O 3), was selected as the dielectric. Al 2 O 3 is already widely used in ceramic coatings by virtue of its excellent mechanical and thermal properties. Furthermore, using pure alumina instead of composite materials as the dielectric material eliminates the complexity of RAC preparation.
