Ceramic filler, method of preparing the ceramic filler and applications as resonator and laminate thereof

摘要

The present disclosure relates to ceramic fillers and methods for preparing said ceramic fillers. The present disclosure further relates to dielectric resonator, fluoropolymer-ceramic filler compositions and their corresponding laminates along with their respective methods for preparing the same from the ceramic fillers. The present disclosure further provides a dielectric resonator and fluoropolymer-ceramic filler laminates having enhanced dielectric properties. The present disclosure also relates to various microwave applications of such fillers, resonators and laminates including microwave devices and circuits.

1. A composition consisting of a fluoropolymer and a ceramic filler, optionally along with glass fibre or industrially acceptable additive, wherein the ceramic filler is represented by a formula M′1-xM″xTaO4;
wherein, M′ and M″ is individually a metal selected from a group comprising aluminum (Al), yttrium (Y), lanthanum (La), praseodymium (Pr), europium (Eu), gadolinium (Gd), terbium (Tb), samarium (Sm) and ytterbium (Yb) or any combination thereof; Ta is tantalum; O4 is derived from a stoichiometric combination of oxides of M′, M″ and Tantalum; and x is any number ranging from 0 to 1 including 0 and 1.
