摘要 利用不同粒度的CaO-B2O3-SiO2(CBS)玻璃粉料,制备了低温烧结的CBS玻璃陶瓷。研究了粉料粒度对CBS系玻璃陶瓷低温烧结的影响。实验表明,粉料粒度对粉料的玻璃化温度Tg的影响不明显,玻璃致密化开始于玻璃化温度Tg≈680℃,随着烧成温度升高,收缩率迅速增大;随着粉料粒度的减小,试样的烧结温度和显气孔率降低,体积密度、收缩率、热膨胀系数和抗折强度都增大。将粉料粒径中位值D50=2.34μm的粉料采用流延工艺制得127μm的生料带,运用优化烧成工艺,与银电极浆料在850℃共烧,表面平整,匹配良好,能在一定程度上满足低温共烧陶瓷(LTCC)用基板材料的要求。 The CaO-B2O3-SiO2(CBS) glass-ceramics were prepared by the powders of different grain sizes.The effect of the grain size of glass powder on the sintering behavior of the glass ceramics was investigated.The experimemtal results showed that the grain size of the glass powder had no significant effect on the glass transition temperature Tg.The glass-ceramics started to densify at about Tg≈680 ℃,then shrinking enlarged rapidly with the sintering temperature increasing.By reducing the grain size of glass powders,the sintered temperature and the apparent porosity decreased,while the bulk density,the shrinkage ratio,the thermal expansivity and the fracture strength increased.By using the casting process,the green tape of 127 μm has been prepared with the powders of grain size D50=2.34 μm.Then it was co-fired with the Ag electrode paste at 850 ℃ by using the optimized firing technology.The obtained CBS glass-ceramics system had no camber and mismatch,which could satisfy with the requirements of the substrate materials used in LTCC.
