Multilayered multifunctional ceramic materials by tape casting

Compatibility studies were performed on several electro-ceramic materials for possible usage in multilayered multifunctional ceramic (MMC) devices. Ceramic tape cast sheets were made using BaTiO/sub 3/, (Ni,Zn)Fe/sub 2/O/sub 4/, and 70% Al/sub 2/O/sub 3/ electrical porcelain powders. These materials were then laminated and co-fired to yield monolithic ceramic blocks. EDS dot maps of the material interfaces show that cross-reactivity between sheets was minimal allowing for their usage in complex 3-D circuitry.
