摘要
通过对堇青石水基流延浆料体系的研究,获得了流动性、稳定性良好的浆料。所制备出的流延坯片可以在较低的温度下烧结,坯片的致密性较好,相对密度较高,且具有良好的介电性能。重点对坯片的叠层进行了研究,结果表明,流延坯片可以在室温下实现良好的叠层。在2.5MPa的压力下,5层坯片结合良好,但当层数增加到10层时,试样中会有气孔出现,烧结性能变差,适当提高叠层的压力可以使烧结性能改善。该方法与热压法相比,叠层的压力和温度均较小;与溶剂法和粘合法相比,不需要额外的添加剂。
Water based tape casting slurry of cordierite with good performances of fluidity and stability was ac- quired via the research of slurry system. The tapes prepared by the slurry could be sintered at low temperature. Moreover, the compactness is better, the relative density is higher and the dielectric properties are good. Lami- nation of green tapes was studied mostly. The results showed that the tapes could be laminated well at ambient temperature. Five green tapes could be bonded well at 2.5MPa. However, pores would appear when the layers increased to 10 and the sintering properties would become worse. The sintering properties could be improved with increasing pressure. Compared with thermo-pressure lamination, the pressure and temperature during lamination are lower; with solvent or gluing based lamination, additional additives are not needed.
