Ceramic dielectric materials that can be utilized as electronic components, such as dielectric resonators are disclosed. The material can have a formula Ba 12 M' (28+a/3) Ti (54-a-b) M" a Ge b O 162 , wherein M' is at least one rare earth element selected from the group consisting of lanthanum, neodymium, samarium, gadolinium, and yttrium, M" is at least one element selected from the group consisting of aluminum, gallium, chromium, indium, scandium, and ytterbium, 0 ‰¤ a ‰¤ 6, and 0 ‰¤ b ‰¤ 3. The ceramic dielectric material can also have a formula Ba 12 M' (28+2x/3) Ti( 54-x-y) M"' x Ge y O 162 , wherein M' is at least one rare earth element selected from the group consisting of lanthanum, neodymium, samarium, gadolinium, and yttrium, M"' is at least one metal selected from the group consisting of magnesium, zinc, nickel, and cobalt, 0 ‰¤ x ‰¤ 3, and 0 ‰¤ y ‰¤ 3. One or more aspects of the present invention pertain to methods of fabricating a dielectric component. Methods of synthesizing the disclosed ceramic dielectric materials are also disclosed. |
