| 摘 要： | 以Li_2O为烧结助剂,采用DTA、XRD、SEM等分析手段研究了添加1.0～2.5 wt%Li_2O对CaO-B_2O_3-SiO_2(CBS)系微晶玻璃性能的影响.结果表明:Li_2O降低了CBS系微晶玻璃的玻璃转变温度和析晶温度.未添加Li_2O的试样在930 ℃烧结,而添加Li_2O的试样可以在820 ℃以下烧结,Li_2O显著降低了试样的烧结温度.当Li_2O添加量为1.0wt%时,试样可以在760～820 ℃范围内烧结,800 ℃烧结试样介电常数为5.71,介电损耗为0.0024(测试频率为10 MHz).

| Abstract: | The effects of 1.0-2.5wt% Li_2O sintering aid on the properties of CaO-B_2O_3-SiO_2(CBS) glass ceramics were investigated by different analytical techniques such as DTA, XRD, SEM. The results show that Li_2O sintering aid decreases glass transition and crystallization temperatures. The sintering temperatures of CBS glass ceramics doped with Li_2O decrease significantly from 930 ℃ to 820 ℃. Adding with 1.0wt% Li_2O, the sintering temperature of the sample is between 760 ℃ and 820 ℃. The dielectric constant and dielectric loss of the sample sintered at 800 ℃ are 5.71 and 0.0024 at 10 MHz, respectively. |
