Title: The Innovations of William Frederick Peck
Introduction
William Frederick Peck is a notable inventor based in Bridgewater, NJ (US). He has made significant contributions to the field of materials science, particularly in the development of dielectric materials. With a total of 2 patents, his work has implications for various electronic applications.
Latest Patents
Peck's latest patents focus on pyrochlore-based oxides with high dielectric constants. One of his notable inventions involves measuring the temperature-dependent dielectric constants of bulk ceramics that are phase mixtures of Pb₂(Nb,Mg,Ti)₂O₆+x pyrochlores and Pb(Nb,Mg,Ti)O₃ perovskites. He discovered a specific composition range where the negative temperature coefficient of dielectric constant for the pyrochlore is closely compensated by the positive temperature coefficient of the perovskite. This results in dielectric constants near 200, with quality factors near 200 at 1 MHz, positioning these materials as an intermediate family of dielectrics.
Another significant patent addresses the compensation of the temperature coefficient of the dielectric constant. Peck found that a decrease in the temperature coefficient for polycrystalline ceramics of Barium Strontium Titanate (BST) can be achieved through admixture with tetragonal bronze type Barium Strontium Niobate (BSN). His research indicates that a 10% admixture of BSN can reduce the temperature coefficient by a factor of 2.5 at 10 MHz, with minimal degradation of dielectric loss. A 37.5% admixture can decrease the temperature coefficient by more than 100, with dielectric constants ranging from 200 to 500.
