Abstract The SrO-BaO-Nb2O5-Al2O3-SiO2 (SBN-AS) based glass ceramics with different ZrO2 content were synthesized via the glass melting process and temperature controlled crystallization. The influences of adding different amounts of ZrO2 on the microstructure, crystallization and dielectric properties of SBN-AS based glass ceramics were investigated. Among the studied SBN-AS based glass ceramics with different ZrO2 content, the dielectric constant of the SBN-AS based glass ceramics increases from108.9 to 135.9 with the ZrO2 content when the ZrO2 is lower than 0.5 mol% and then decreases when higher than 1.0 mol%. The breakdown strength of the SBN-AS based glass ceramics first gradually increases from 1111.2 to 1129.4 kV/cm with the ZrO2 content and then increases quickly from 1291.6 to 1377.7 kV/cm when the ZrO2 content is higher than 1.0 mol%. For the 1.0 mol% of ZrO2 content added, the maximum value of energy storage density for the resulting glass-ceramic is 8.9 J/cm3, which is about 113% greater than that of the SBN-AS based glass ceramic without ZrO2 addition. The enhanced energy storage density could be attributed to a few ZrO2 content added into the SBN-AS based glass ceramics as nucleating agents at and excess content ZrO2 as network agents.

添加ZrO2的SrO-BaO-Nb2O5-Al2O3-SiO2基玻璃陶瓷的结晶、微观结构和介电性能

摘要 通过玻璃熔融工艺和温控结晶合成了不同ZrO2含量的SrO-BaO-Nb2O5-Al2O3-SiO2(SBN-AS)基微晶玻璃。研究了不同ZrO2添加量对SBN-AS基微晶玻璃微结构、结晶和介电性能的影响。在研究的不同ZrO2含量的SBN-AS基微晶玻璃中，当ZrO2含量低于0.5 mol%时，SBN-AS基微晶玻璃的介电常数随着ZrO2含量的增加从108.9增加到135.9，高于1.0 摩尔％。SBN-AS基微晶玻璃的击穿强度随着ZrO2含量的增加先从1111.2逐渐增加到1129.4 kV/cm，然后当ZrO2含量高于1.0 mol%时从1291.6快速增加到1377.7 kV/cm。添加1.0 mol%的ZrO2后，所得微晶玻璃的储能密度最大值为8.9 J/cm3，比未添加ZrO2的SBN-AS基微晶玻璃的储能密度高出约113%。增强的储能密度可归因于在 SBN-AS 基玻璃陶瓷中添加少量 ZrO2 作为成核剂和过量的 ZrO2 作为网络剂。
