(ProQuest: Formulae and/or non-USASCII text omitted; see image) ceramic powders were synthesized by the sol-gel method using ethylenediaminetetraacetic acids as chelating agent. Various techniques were used to characterize the precursors, powders and sintered ceramics. The microwave dielectric properties of (ProQuest: Formulae and/or non-USASCII text omitted; see image) ceramics sintered at different temperatures were also measured. Well-crystallized powders with about 80 nm particle size were obtained by calcination of the pulverized resins at 900 °C for 3 h in air. The (ProQuest: Formulae and/or non-USASCII text omitted; see image) (x=2/3) ceramics sintered at 1340 °C for 3 h had excellent microwave dielectric characteristics: ε=87.1, Qf=8710 GHz.[PUBLICATION ABSTRACT]
