In this paper, the phase compositions and the dielectric properties of 3ZnO-2B(2)O(3) glass-ceramic prepared by solid-state method were investigated. The X-ray diffraction patterns show that all sintered samples consist of Zn3B2O6 and -Zn(BO2)(2). The dielectric properties changed significantly with the sintering temperature. After sintering at 650 degrees C for 30min, the glass-ceramic exhibits optimum dielectric properties: a dielectric constant of 7.5 and a dielectric loss of 0.6x10(-3) at 10MHz. The chemical compatibility with Ag electrode under the co-fired process illustrates a potential application in low temperature co-fired ceramic field for the glass-ceramic.
