The phase transition behavior, density and dielectric properties were studied by the X-ray diffraction, scanning electron microscopy and impedance analysis. The results show that the best calcining temperature range for this system is 750–780℃.The relative dielectric constant (εr) and dielectric loss(tanδ) of the oxyfluoride glass-ceramics/silicon dioxide system decrease with the increasing of sintering temperature because part of the amorphous glass phase is transformed into cristobalite phase. The sample reaches the maximum bulk density (2.31g/cm3), and the εr decreases to 4.42. The tanδalso falls to approximately 3×10–3 at 1GHz when the samples are calcined at 780℃. The system is promising as a candidate for a new dielectric material for low temperature co-fired ceramic substrate, passive integration and packaging technology.Key words: oxyfluoride glass-ceramics; low temperature co-fired ceramic; glass-ceramic; dielectric properties近年来,随着电子信息技术的飞速发展,对电子元器件微型化、集成化和高频化的要求不断提高。在制作多层元件或把无源器件埋入多层电路基板中的过程中,选择适当的能与银等导电材料在低温(低于900℃)实现共烧[1–2],[3]21–23的电子封装材料,成为上述研究的关键。目前在众多的封装技术中,利用低温共烧陶瓷(low temperature co-fired ceramic,LTCC)技术制备的片式无源集成器件不仅具备高频高品质特性,而且还具备高可靠性、优良的电性能和密封性能。[1,4–6]目前,高频低介电常数电子封装陶瓷由于有利于提高信号的传输速率、降低信号的延迟时间而成收稿日期:2010–04–05。修改稿收到日期:2010–07–28。基金项目:国家自然科学基金(50902081),国家“973”计划(2009CB62- 3304),国家“863”计划(2007AA03Z449)和广东省省部产学研(2009A090100021)资助项目。第一作者:王阳培华(1983—),男,硕士研究生。通信作者:李勃(1976—),男,博士,副教授。Received date:2010–04–05.
