Effects of CeO₂ Additions on the Structure and Dielectric Properties of Aluminoborosilicate Glasses

Abstract:

Glasses with compositions 15Al₂O₃-20B₂O₃-50SiO₂-5CaO-(10-x)MgO-xCeO₂ (x=0, 1, 2 and 3 mol %) were prepared by conventional melting method. Fourier-transform infrared spectroscopy (FTIR) indicated that the addition of CeO₂ converted trigonal boron (^[B) to tetrahedral boron (^[B). The glass transition temperatures (T_g) were determined using a differential scanning calorimetry (DSC). T_g increased with increasing CeO₂ content. Thus, the addition of CeO₂ instead of MgO strengthened the glass network. The dielectric constant ε_r and loss tanδ were measured for these glasses at 10⁵ Hz. The decrease in ε_r and tanδ could be attributed to the increase in the rigidity of the glass network as the CeO₂ content increased.
