摘要： A dielectric ceramic composition which is suitable as the material of ceramic capacitors and has a high permittivity, a low rate of change in permittivity with temperature, a high insulation resistance, high mechanical strengths, a low sintering temperature dependence of electrical properties, and a small sintered particle diameter. Since it can be sintered in a temperature range as low as 1000 DEG C or below, an inexpensive base metal can be used as an internal electrode. It has the following composition: [Pb(Mg1/2W1/2)O3]X-[Pb(M1/3Nb2/3)O3]Y-[PbTiO3]Z-[PbZrO3]U wherein M represents Ni or Mg and X, Y, Z and U each represents a molar fraction, wherein X+Y+Z+U=1, and satisfies the following relations: 0.05

摘要： A capacitor includes a pair of electrodes and a metalized dielectric layer disposed between the pair of electrodes, in which the metalized dielectric layer has a plurality of metal aggregates distributed within a dielectric material. The distribution is such that a volume fraction of metal in the metalized dielectric layer is at least about 30%. Meanwhile, the plurality of metal aggregates are separated from one another by the dielectric material. A method for forming a metal-dielectric composite may include coating a plurality of dielectric particles with a metal to form a plurality of metal-coated dielectric particles and sintering the plurality of metal-coated dielectric particles at a temperature of at least about 750° C. to about 950° C. to transform the metal coatings into discrete, separated metal aggregates. Contrary to conventional techniques of separating electrodes by a dielectric tape, this inventive system and method demonstrates that a metalized dielectric layer may be formed in-situ during sintering.
