A thick-film aluminum (Al) electrode paste is provided to fabricate a chip resistor. The paste is a mixture of a vanadium-zinc-boron series glass (V.sub.2O.sub.5ZnOB.sub.2O.sub.3 or BaOZnOB.sub.2O.sub.3) along with a metal oxide, aluminum granules, and an organic additive, whose proportions are separately 330 wt %, 0.115 wt %, 5070 wt %, and 1020 wt %. After being stirred through three rollers and filtered, the paste is pasted on an alumina ceramic substrate. The pasted substrate is dried and sintered for forming a thick-film aluminum electrode. Meanwhile, before processing metal plating that follows, an anti-plating pretreatment is performed. Therein, surface irregularities and nonconductive alumina on the surface are removed. Thus, the electrode obtains smooth flat surface and low oxygen content. The characteristics of the chip resistor using the thick-film aluminum electrode are equivalent to those using thick-film printed silver electrodes and those using thick-film printed copper electrodes sintered in a reducing atmosphere.

The present invention provides a dental glass composition that has excellent fixability to dental prostheses, and that does not need firing and fixing to layer color or enable a build-up of porcelain thereon. The present invention relates to a dental glass composition comprising a glass powder (A) and a wax component (B). The glass powder (A) has an average particle diameter of preferably 0.05 m to 50 m.

Ceramics and glass-ceramics have low and/or negative coefficients of thermal expansion. Crystalline phases of the formula AM.sub.2Si.sub.2-yGe.sub.yO.sub.7 (A=Sr and Ba and M=Zn, Mg, Ni, Co, Fe, Cu, Mn, with Sr, Ba and Zn necessarily having to be present) can be produced by conventional ceramic processes or by crystallization from glasses. The compositions form solid solutions, where the elements indicated as component M can be replaced by one another in virtually any concentration but the concentration of Zn must always be at least 50% of the sum of all components indicated under M. The stoichiometry of these silicates and also their structure can differ to a greater or lesser extent.

In some examples, method including forming an EBC layer on a substrate, wherein the EBC layer exhibits an initial porosity; forming a layer of silicate glass on a surface of the EBC layer; and melting the silicate glass on the surface of the EBC layer to infiltrate the EBC layer with the molten silicate glass to decrease the porosity of the EBC layer from the initial porosity to a final porosity.

A powder magnetic core having excellent specific resistance or strength. The powder magnetic core has soft magnetic particles, first coating layers that coat the surfaces of the soft magnetic particles and include aluminum nitride, and second coating layers that coat at least a part of the surfaces of the first coating layers and include a low-melting-point glass having a softening point lower than an annealing temperature for the soft magnetic particles. The first coating layers including aluminum nitride are excellent in the wettability to the low-melting-point glass which constitutes the second coating layers and suppress diffusion of constitutional elements between the soft magnetic particles and the low-melting-point glass of the second coating layers. The powder magnetic core can stably exhibit a higher specific resistance and higher strength than the prior art owing to such a synergistic action of the first coating layers and second coating layers.
