A glass system according to the molar formula (35% mole SiO2- 40% mole B2O3 -(25-x) Li2O), where x=0,1,2 and 3 % mole Fe2O3, was prepared by melting the pure powder chemicals at porcelain crucibles at 1200Co for three hours until the homogenous glass was obtained. The samples were heat treated at 600 and 700 Co for 10 hours. The density, the molar volume, the electrical conductivity and magnetic properties were measured before and after the heat treatment. Replacing the lithium oxide with the iron oxide increases the density, the electrical and magnetic properties. The heat treatment decreases the electrical conductivity and the magnetic susceptibility while increases the density. The crystalline phases due to heat treatment were determined using x-ray diffraction.
