Abstract:
The dielectric composition contains a mixture of a ceramic composition containing BaaREbTicO3, wherein RE represents a rare earth element, with 0.05≦a≦0.25, 0.525≦b≦0.70, 0.85≦c≦1.0, and 2a+3b+4c=6, and free from lead and bismuth, a glass composition, and a metal oxide. The glass composition preferably contains ZnO or MgO, SiO2, and at least 10% by weight of Li2O or TiO2. Preferably, the alkaline earth metal oxide is MgO. By preference, the glass composition essentially consists of 50-80% weight of SiO2, 5-25% weight of MgO, and optionally another alkaline earth metal oxide, and 10-25% by weight of Li2O, and is substantially free from boron. The dielectric composition can be sintered in the presence of Cu electrodes at a temperature below the melting point of Cu so as to manufacture an electronic device such as a ceramic multilayer element. After sintering, the dielectric composition has a relative dielectric constant of at least 55.
Abstract:
A gas discharge lamp with at least one capacitive coupling structure (2, 3) is described, which lamp has the particular characteristic that the coupling structure (2, 3) comprises a ceramic material which comprises pure BaTiO3. In particular an additional doping of at least part of the BaTiO3 with barium leads to a material whose Curie temperature and saturation polarization are substantially higher and whose coercitive field strength is substantially smaller, so that a gas discharge lamp with a coupling structure manufactured from this material can be operated at substantially higher temperatures and at a lower operating voltage. Various dopings of the BaTiO3 with titanium, manganese, and lead are furthermore described.
