A ceramic composition for dielectrics, consisting essentially of an inorganic dielectric material including at least one electrically insulating glass and at least one organic binder, and further comprising at least one inorganic peroxide. The inorganic peroxide serves to facilitate burnout or removal of the organic binder during firing of the ceramic composition and minimizes the content of residual carbon in the fired ceramic composition. The inorganic peroxide is preferably selected from the group consisting of calcium peroxide, strontium peroxide, barium peroxide, zinc peroxide and cadmium peroxide, and present preferably in an amount of 0.1-40% by weight. Also disclosed is a process of manufacturing a ceramic circuit board using the ceramic composition stated above.
A ceramic composition for an electronic circuit board, a hybrid integrated circuit, an integrated circuit package or a multilayer ceramic structure, consisting essentially of at least one electrically insulating glass, at least one organic binder, at least one inorganic peroxide, and at least one material selected from the group which consists of: a metal selected from the platinum group; a compound of the platinum group; a manganese oxide; and a cobalt oxide.
A process for the preparation of molten mineral compositions wherein organic impurities are removed by reaction with oxygen introduced via the decomposition of calcium peroxide.
Dielectric ink, paste and tape compositions having controlled thermal expansion contain a mixture of glasses wherein at least one glass has a coefficient of thermal expansion (CTE) below the CTE of the substrate to which the dielectric composition is applied and at least one glass has a CTE above the CTE of said substrate. The dielectric compositions significantly reduce or eliminate warpage of the substrate.
An insulating powder for the formation of a resistant coating is disclosed which comprises a glass powder consisting of 60 to 70% by weight of ZnO, 19 to 25% by weight of B.sub.2 O.sub.3, and 10 to 16% by weight of SiO.sub.2. A composition for the formation of a resistant coating is also disclosed which comprises the powdered oxide of a platinum-family element; the powder of at least one oxide selected from the group consisting of indium oxides, tin oxides, and cadmium oxides; a glass powder capable of forming a crystalline phase on being fired; a ceramic powder; and an organic vehicle.
Disclosed herein is a method of manufacturing a ceramic laminate which is adapted to manufacture a laminated ceramic capacitor, for example. This method comprises the steps of preparing a plurality of ceramic green sheets containing ceramic powder and a first binder, forming metal paste films containing metal powder and a second binder for providing internal electrodes on first major surfaces of the ceramic green sheets and stacking the plurality of ceramic green sheets with each other. In such a method, a junction member containing a solvent which can commonly dissolve the first and second binders is prepared in order to join the plurality of ceramic green sheets with no application of pressure, to be applied between adjacent pairs of the plurality of ceramic green sheets, which are stacked with each other. The junction member is adapted to join the adjacent pairs of ceramic green sheets with each other through chemical function.
