Abstract:
The formula of nucleated glass ceramics for high-frequency chip inductor comprises five components of CaO, B2O3, SiO2, ZnO and P2O5, and their mixing ratio is: CaO 25-60 wt%, B2O3 10-50 wt%, SiO2 10-60 wt%, ZnO 1-10 wt% and P2O5 1-5 wt%. Said invented nucleated galss ceramics product possesses low dielectric constant (epsilon=4.9-5.5,1MHz), and its sintering temp. is lower (750-850 deg.C). The present invention also provides its preparation method.
