TY - JOUR A1 - Naghib Zadeh, Hamid A1 - Glitzky, Carsten A1 - Dörfel, Ilona A1 - Rabe, Torsten T1 - Low temperature sintering of barium titanate ceramics assisted by addition of lithium fluoride-containing sintering additives JF - Journal of the European Ceramic Society N2 - By addition of LiF-containing sintering additives to commercial BaTiO3 powder, more than 98% of the theoretical density was reached at a sintering temperature of 900 °C both on powder compacts and laminates. Dielectric measurements were performed on ceramic samples in the temperature and frequency ranges from -20 °C to 125 °C and from 103 to 106 Hz, respectively. High relative permittivity (εr ~ 3160) and low dielectric loss (tan δ ~ 0.014) were measured for tapes of the favoured material. The breakdown strength for tapes with a thickness of about 80 µm is 30 kV/mm. The microprobe analysis showed, that no interfacial reaction between the dielectric layer and the Ag-electrode had occurred. The newly developed barium titanate ceramics completely densifying at 900 °C turned out to be promising for integration of buried capacitors in LTCC multilayers.
