摘要:
A glass-ceramic composition contains first ceramic particles principally containing forsterite; second ceramic particles principally containing at least one selected from the group consisting of calcium titanate, strontium titanate, and titanium oxide; and borosilicate glass particles containing about 3% to 15% lithium oxide, about 20% to 50% magnesium oxide, about 15% to 30% boron oxide, about 10% to 45% silicon oxide, about 6% to 20% zinc oxide, 0% to about 15% aluminum oxide, and at least one additive selected from the group consisting of calcium oxide, barium oxide, and strontium oxide on a weight basis. The content of the borosilicate glass particles is about 3% or more; the lower limit of the content of the additive is about 2%; and the upper limit of the additive content is about 15%, about 25%, or about 25% when the additive is calcium oxide, barium oxide, or strontium oxide, respectively, on a weight basis.
摘要:
An insulating ceramic composition forming insulating ceramic layers (3) stacked in a multilayer ceramic substrate (2) used in a monolithic ceramic electronic component, such as a multilayer ceramic module (1). The insulating ceramic composition contains a first ceramic powder mainly containing forsterite, a second ceramic powder mainly containing at least one compound selected from the group consisting of CaTiO3, SrTiO3, and TiO2, and a borosilicate glass powder. The borosilicate glass powder contains 3 to 15 percent by weight of lithium in terms of Li2O, 30 to 50 percent by weight of magnesium in terms of MgO, 15 to 30 percent by weight of boron in terms of B2O3, 10 to 35 percent by weight of silicon in terms of SiO2, 6 to 20 percent by weight of zinc in terms of ZnO, and 0 to 15 percent by weight of aluminum in terms of Al2O3. The insulating ceramic composition can be fired at a temperature of 1000° C. or less, and the resulting sintered compact has a low relative dielectric constant, a resonance frequency with a low temperature coefficient, and a high Q value.

摘要:
An electrically conductive paste used for forming wiring conductors, such as via holes (15) disposed on a multilayer ceramic substrate (11), is provided, wherein the temperature range, in which sintering is effected in a firing step, can be controlled relatively optimally. The electrically conductive paste contains a metal powder, a grass frit, and an organic vehicle. An inorganic component, which is not sintered at a sintering temperature capable of sintering the ceramic layers (12) included in the multilayer ceramic substrate (11) in the firing step, is disposed on particle surfaces of the metal powder. The glass frit has a softening point 150° C. to 300° C. lower than the above-described sintering temperature.
