Effect of CaO-B2O3-SiO2 glass on the magnetic and dielectric properties of NiCuZn ferrites

► Glass system CaO-B2O3-SiO2 used for liquid-phase sintering for NiCuZn ferrites. ► Ms increased first and reached its maximum at x=2, whereupon it began to decrease. ► Permeability decreases continually and the downtrend slows with the increase in x. ► Permittivity increases significantly with the increase in x. ► NiCuZn ferrite co-fired with CaO-B2O3-SiO2 exhibit the compatibility of magnetic and dielectric properties.
