Structure and microwave dielectric characteristics of Sr(La_1−xSm_x)₂Al₂O₇ceramics

Abstract

Sr(La1−xSmx)2Al2O7 (0 ≤ x ≤ 1) ceramics were synthesized by a standard solid-state reaction method, and the microwave dielectric characteristics were investigated together with the densification behavior, microstructure and phase composition.

Microstructure and sintering behavior of low temperature cofired Li4/5Mg4/5Ti7/5O4 ceramics containing BaCu(B2O5) and TiO2 and their compatibility with a silver electrode

“…By further increasing the sintering temperature, the average grain size increased, because grains continued to arise. On the other hand, the velocity of the grain boundary was too fast when the sintering temperature was too high, making the elimination of pores difficult, 18,19 so the porosity increased. The change in porosity resulted in a change of the bulk density.…”
