Patent ID: 8562899

Claim:
A method of making an electronically tunable dielectric material, the method comprising: mixing particles of at least one electronically tunable dielectric material and a total of from about 1 to about 80 weight percent of particles of at least two additional metal oxide materials, wherein the at least two additional metal oxide materials are selected from a group consisting of WO 3 , SnTiO 4 , ZrTiO 4 , CaSiO 3 , CaWO 4 , CaZrO 3 , PbO and Bi 2 O 3 ; sintering the mixture of the particles, wherein the electronically tunable dielectric particles and the additional metal oxide particles have average particle sizes of from about 0.1 to about 5 micron; forming the electronically tunable dielectric material from the sintered mixture of the particles; measuring a dielectric constant, a tunability and a dielectric loss for the formed electronically tunable dielectric material; adjusting an amount of only one metal oxide material of the at least two additional metal oxide materials for a subsequent mixing step; and repeating the mixing, sintering, forming, measuring and adjusting steps to change the dielectric constant of the formed electronically tunable dielectric material to a desired dielectric constant while maintaining the tunability and the dielectric loss of the formed electronically tunable dielectric material substantially the same.
