Investigation of Low‐Temperature Sintering Mechanism on BaONd₂O₃TiO₂ Dielectric Ceramics with Li₂OB₂O₃‐SiO₂ and BaOZnOB₂O₃ Glasses

Abstract

In this paper, the BaO─Nd 2 O 3 ─TiO 2 (BNT) ceramics are synthesized at low temperature with the assistance of Li 2 O─B 2 O 3 ─SiO 2 (LBS) and BaO─Z-nO─B 2 O 3 (BZB) glasses. The influences of glasses on the sintering behavior, phase composition, microstructure, activation energy (E a ) on the BNT ceramics are studied in detail. The results show that a new phase, Ba 2 LiB 5 O 10 , is formed from the chemical reaction between LBS and BZB glasses. The sintering temperature of BNT ceramics can be effectively reduced by 450 C due to the synergetic effect of LBS and BZB glasses and the appearance of Ba 2 LiB 5 O 10 phase.

“…Compared with the pure BNTCN ceramic, the sample at x = 5 presented three endothermic peaks in the temperature range of 730~750°C. These peaks were identified as endothermic melting peaks 15 . As described in the experimental procedures, the LB glass consists of the L and B glass.…”

“…These peaks were identified as endothermic melting peaks. 15 As described in the experimental procedures, the LB glass consists of the L and B glass. Hence, the DSC peaks at 730.4°C and 741.9°C could be recognized as the melting temperature of B and L glass, respectively.…”
