Effect of ZrO2 Doping on Properties of BaO–B2O3–SiO2 Glass-ceramics
Abstract:BaO–B2O3–SiO2 glass-ceramic with high thermal expansion behavior were prepared by a solid-state method. Thermal, mechanic, electric properties of glass-ceramic composite materials and its scanning electron microscope, X–ray diffractometer and differential scanning calorimetry were used to research the effect of ZrO2 doping on the properties of BaO–B2O3–SiO2 glass-ceramic. The results show that as the ZrO2 doped content increases, microscopic, the cristobalite phase of glass-ceramic content reduced significantly, the quartz crystal phase content increased significantly; macroscopic, the bending strength and the relative permittivity of the glass-ceramic gradually increase, the thermal expansion coefficient gradually decrease slightly, the high thermal expansion coefficient can be adjusted by doping ZrO2, the thermal expansion coefficient changes with temperature tend to be more linear, optimized the thermal properties of glass-ceramic. When sintering temperature is 950 , ZrO2 doped content is 5%, BaO–B2O3–SiO2 glass ceramics were obtained with maximum bending strength (181 MPa), higher CTE (14.21 × 10-6/), lower relative dielectric constant (6.4) and lower dielectric loss (0.4%). This glass ceramics can meet the requirement of glass ceramics low temperature co-fired ceramics package materials.
