The influence of different solvent systems and the dispersant content on the rheological properties of glass/alumina were investigated using efficient tape casting technology.Slurry formulations were optimized by the method of changing the ration of the inorganic to the total present in tape and the ration of plasticizer to binder.The effect of tape-casting slurry composition on bulk density of green tape and bulk density,micro-structure and phase of the sintered samples was studied in detail.The results showed that the appropriate com-position and content of slurries improved bulk density,dielectric properties and microstructure of sintered sam-ples.The samples sintered at 850 ℃ had a dielectric constant of 7.7,a dielectric loss of 2.0×10-4 and a ther-mal expansion coefficient of (7.30-7.65)×10-6/℃ in the range of 25-500 ℃,which satisfied with the require-ments of LTCC packaging materials.
