采用XRD、SEM、DSC等测试分析手段研究了Ca/Si比变化对CBS微晶玻璃晶相、微观结构和电性能的影响。结果表明在固定B2O3的含量为17%（摩尔分数）时,发现当m（Ca/Si比）〈1.08时,CBS微晶玻璃的烧结温度〉900℃,当m〉1.08时,CBS微晶玻璃的烧结温度900℃。当m达到1.767时,CBS微晶玻璃无法烧结;随着CaO含量的增加,Ca2SiO4晶体逐渐增加,硅灰石相逐渐减少,石英相逐渐增加;在1MHz下,C2、C5和C7试样烧结后电损耗均〈2×10-3。
Influence of Ca/Si on the crystallization,microstructure and dielectric properties of CaO-B2O3-SiO2 glass was studied by using XRD,DSC and SEM.The results indicate that when m（Ca/Si ratio）1.08,calcium borosilicate glass sintering temperature higher than 900℃,but it is m1.08,CBS department of the sintering temperature of glass is far lower at 900℃.When m reaches 1.767,CBS can not be sintered;with the increase of CaO content,Ca2SiO4 crystals gradually increased,leading to the gradual reduction of wollastonite phase,resulting in gradual increase in quartz;the samples were C2,C5,C7 dielectric loss sintered 2×10-3 at 1MHz.
