Scholarcy highlights

  • This study discusses aluminoborosilicate glasses with La2O3 and CeO2
  • There dips in dielectric constant and loss at the most compact structure
  • Structural, thermal, and dielectric properties were investigated by FTIR, DSC, and impedance analyzer
  • Results indicate that more Q3 and Q4 would form at the sample with the same amount of La2O3 and CeO2, meaning the most compact structure, while more La2O3 would lead to a loosen network
  • Glasses obtained the best dielectric properties here, and the dips in dielectric constant and loss are ascribed to the structural changes in the glass network
  • The glass density gradually increases, which is mainly from the small field strength of La3+ ions and the larger molar mass of La2O3
