摘　　要：分别考察氟和磷对SiO2-Al2O3-B2O3系统玻璃介电性能的影响。结果表明:随着氟含量的升高,玻璃介电常数和介质损耗均有所下降,但当氟含量超过3.8%时,变化不再明显;随着P2O5含量的增加,介电常数呈逐步降低的趋势,但降低幅度不大,当P2O5含量在4.5%时介电常数降到最低,而介质损耗则出现先下降后上升的趋势。随着氟、磷含量的增加,玻璃失透温度范围均增大。Dielectric properties of glass with different composition selected from a SiO2-Al2O3-B2O3 system were investigated.Different contents of fluoride and phosphorus pentoxide were analyzed,respectively.Results show that when the fluorine content increases,the dielectric constant and dielectric loss decrease;when the phosphorus pentoxide content increases,the dielectric constant tends to reduce gradually.Compared with glass without phosphorus pentoxide,the dielectric constant is lower than 0.13,in which the glass has 4.5% phosphorus pentoxide.The dielectric loss has a rising trend after first declining,but overall change is little.
