The present invention provides a new and useful via fill paste for use in the construction of electronic circuit devices. The unique via fill paste is capable of electrically connecting conductive layers made of dissimilar metals such as gold and silver. The via fill paste includes gold, silver, palladium and a refractory oxide. The refractory oxide comprises one or more metals selected from the group consisting of zirconium, yttrium, niobium, tantalum, lanthanum, thorium, hafnium, cerium, praseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium and lutetium.

The present invention provides a method for making an insulated electrical heating element such as for domestic appliances to heat water, etc. wherein a resistive track is embedded in a dielectric ceramic insulating material. The method includes the steps of providing a rigid base plate; printing a resistive track on one surface of a segment of flexible tape comprising fusible ceramic particles in an organic binder; adhering the other surface of the tape segment to a surface of a base plate; and placing a second segment of flexible tape of the same type on the surface with the resistive track printed thereon. Then the resulting assembly is fired to fuse the ceramic particles of the tape segments and provide a ceramic layer on the base plate with an electrical resistive track insulated therewithin.

The invention provides a metallic composition and methods for making and using the same. In a preferred embodiment the metallic composition forms a conductor path and is bonded to a substrate of aluminum nitride. The metallic composition comprises Mo, Si, Cu and Mn. The Si may be present in the metallic composition as MoSi. sub. 2. The metallic composition may be produced by firing a paste that has been applied to a substrate of aluminum nitride. The paste comprises an organic vehicle and a metallic powder. The metallic powder preferably comprises about 60% to about 90% by weight Mo, about 0. 5% to about 15% by weight MoSi. sub. 2, about 5% to about 20% Cu and up to about 20% by weight Mn.
