CaO-B2O3-SiO2微晶玻璃的制备及介电性能
Preparation and Dielectric Properties of CaO-B2O3-SiO2 Glass-Ceramics
摘要
Abstract
Glass-ceramics with low dielectric constant and low dielectric loss is an important material for the manufacture of low temperature cofired ceramic substrates.CaO-B2O3-SiO2(CBS)glass-ceramics was prepared by melt-water quenching method,and the effects of m(CaO)/m(SiO2)mass ratio and B2O3 content on the dielectric properties of CBS glass-ceramics were studied.The results show that the main crystalline phases of CBS glass-ceramics are Ca3Si3O9,Ca2B2O5,CaB2O4,SiO2 and Ca2 SiO4.The dielectric constant increases,the dielectric loss decreases first and then increases with the increase of m(CaO)/m(SiO2)mass ratio.The increase of wollastonite phase decreases the dielectric loss from 2.87 x 10-3 to 1.36 x 10-3.The dielectric loss increases with the increase of SiO2,Ca2B2O5 and CaB2O4 content.With the increase of B2O3 content,the dielectric constant increases first and then decreases,and the dielectric loss is reversed.When m(CaO)/m(SiO2)mass ratio is 0.89 and B2O3 content is 15％(mass fraction),the coefficient of thermal expansion is 7.16 x 10-6 ℃-1,the dielectric constant is 5.85,and the dielectric loss is 1.37 × 10-3(10 GHz)after sintering at 900 ℃ for 3 h.关键词
