Heat‐Resistant Ceramic Pigments on the Base of Waste Vanadium Catalyst and Alumina

Journal of Waste Management, Volume 2013, Issue 1, 2013., 2013
Ceramic pigments on the base of technogenic silica‐containing material—waste vanadium catalyst were obtained in this work. Corundum is identified along with the predominant mullite phase in the composition of pigments. The ions of nickel, chromium, and iron are embedded in the structure if the concentration of the corresponding oxide in the initial ...

Thick Film Circuit Layout and Extraction of Parameters Using The Magic Layout Editor

Active and Passive Electronic Components, Volume 14, Issue 2, Page 67-80, 1990., 1990
A Technology file for the Magic layout editor has been developed in order to enable thick film circuit designers to evolve fast solutions for layout with design rule checking, and plotting of the masks of multilayer hybrid circuits. The hybrid design system developed provides for device placement, and automatic routing techniques, in thick film ...

Stability and Performance Characterization of Thick Film Microresistors

Active and Passive Electronic Components, Volume 12, Issue 4, Page 231-237, 1987., 1987
In recent years, interest in the performance of small dimension resistors has increased primarily due to the need to reduce parasitic resistance in high frequency applications. This paper presents results on the characterization of thick film microresistors, i.e. resistors of 80 × 80 mil to 10 × 10 mil dimension.

Raman identification of pigments and opacifiers: Interest and limitation of multivariate analysis by comparison with solid state spectroscopical approach—I. Lead‐tin and Naples Yellow

Journal of Raman Spectroscopy, Volume 55, Issue 2, Page 161-183, February 2024.
Lead‐tin/antimony pigments provide a bright yellow color, which is also often used in combination with a blue‐colored glass to obtain a variety of green hues. From the analysis of the yellow pigments of enameled objects from 18th century French and Chinese productions, the most representative Raman signatures were categorized with those previously ...
