โœฆ Synopsis

The sinterability of Ba(Mgl/3Ta2/3)O 3 ceramics synthesized by solid-state-reaction methods was investigated. The poor sinterability of the present ceramics was found to be primarily due to the presence of satellite secondary phases of BasTa4015 and Ba4Ta20 ~, and the nearly complete densification of Ba(Mgl/3Ta2/3)O 3 ceramics was accomplished successfully by controlling the phase constitution of the calcined powders. For this purpose, enhanced ballmilling processes were found to be extremely effective. Moreover, excellent microwave dielectric characteristics (~r = 24.5-24.7, Q = 26 000 at 9.8 G Hz, and -of = 1.7 p.p.m. ยฐC-1 ) were attained in the dense Ba(Mgl/3Ta2/3)O 3 ceramics without additives.

This paper discusses the difference in permittivity at infrared frequencies between Ba(Mg 1/3 Ta 2/3 )O 3 (BMT) and Ba(Mg 1/3 Nb 2/3 )O 3 (BMN) based on a first-principles calculation. The permittivity, far-infrared and Raman spectra are successfully computed. Analysis of these results shows that th
