Barium Magnesium Tantalate

Perovskites of the type Ba(A_1/3B_2/3)O3 where A = Mg , Zn and B = Ta ,Nb, have created significant interest related to their excellent microwave dielectric properties. Of this group, Barium Magnesium Tantalate has generated considerable interest as a near ideal material for dielectric resonator applications due to its high dielectric constant and unloaded quality factor and, its very low resonant frequency temperature dependence.
