Abstract

<abstract abstract-type="author" id="abs0005"> <title id="sect0005">Abstract</title> <sec> <p id="spar0005">The sintering behavior and electric properties of multilayer laminates made from tapes of CaCu₃Ti₄O₁₂ (CCTO) with glass additive were studied. Sintering at 900 °C gives a fine-grained microstructure with a permittivity of <italic>ɛ</italic>′ = 900. The co-firing behavior of hetero-laminates of CCTO and commercial CT700 glass–ceramic LTCC tapes as well as with polycrystalline zinc titanate (ZT) LTCC tapes was studied. Co-firing of both hetero-laminates is possible, however, cracking due to shrinkage and thermal expansion mismatch was observed in the CCTO/CT700 combination. Co-fired CCTO/ZT multilayer laminates did not show any cracks, delaminations or other defects. CCTO multilayer capacitor elements were integrated into LTCC zinc titanate multilayer laminates and co-fired at 900 °C with AgPd electrodes.</p> </sec> </abstract>
