Abstract
Disclosed are embodiments of a barium magnesium tantalate including additional components to increase the Q value of the material. In some embodiments, complex tungsten oxides and/or hexagonal perovskite crystal structures can be added into the barium magnesium tantalate to provide for advantageous properties. In some embodiments, no tin is used in the formation of the material.
