Gas discharge lamp

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.
