Structural, electrical and thermal properties of borosilicate glass–alumina composites

► Borosilicate glass-10vol.% Al2O3 composites had the lowest dielectric constant. ► Borosilicate glass-10vol.% Al2O3 composites exhibited the lowest thermal expansion. ► Al2O3 addition increased electrical conductivity of the composites. ► Dense composites were obtained by sintering at 1000°C if Al2...
