Conducting nanowires in insulating ceramics

Nature Materials, 2003
Low-dimensional structures, such as microclusters, quantum dots and one- or two-dimensional (1D or 2D) quantum wires, are of scientific and technological interest due to their unusual physical properties, which are quite different from those in the bulk.

Dielectric Evaluation of Ceramic Insulated Wires

2007 IEEE International Conference on Solid Dielectrics, 2007
This paper describes the results of dielectric studies of commercially available "Ceramawire" and "Fujithermo M" ceramic insulated wires have been conducted at selected temperatures in the range of 20 °C to 400°C. The current-voltage characteristics provide information on conduction mechanisms and changes in the magnitude of the leakage current with ...

Epoxy–nanocomposites with ceramic reinforcement for electrical insulation

Journal of Applied Polymer Science, 2011
AbstractCeramic nanoparticles, that is, SiO2, TiO2, and Al2O3nanoparticles, with increasingly high thermal conductivity (λ), represent good candidates for improving the thermophysical properties of epoxy resins. In this study, the influence of filler addition on the thermal, mechanical, and dielectric properties were investigated by means of ...

Additive manufacturing of ceramic insulators

Materials Today: Proceedings, 2020
Abstract Ceramic samples were fabricated from alumina using traditional and additive technologies. Slipcasting technique was used to prepare sample as a traditional way, from pink alumina ceramic slurry with further drying a high temperature treatment of dried preformed ceramics.

Punchthrough of ceramic insulators

Annual Conference on Electrical Insulation and Dielectric Phenomena, 2002
A study of punchthrough breakdown in an alumina insulator is presented. The alumina cylinder, containing electrodes at 300 kV in a vacuum of 10/sup -6/ torr, experienced permanent puncture damage from a breakdown process that was unexpected because the fields from the electrodes were well below the breakdown strength of the ceramic.

Effects of Flash Sintering Parameters on Insulation Performance of Ceramic Insulator

2020 IEEE International Conference on High Voltage Engineering and Application (ICHVE), 2020
Ceramic outdoor insulators play an important role in electrical insulation and mechanical support because of the good chemical and thermal stability, which have been widely used in both transmission and distribution power system. However, the brittleness and surface discharge of ceramic material greatly limit the application of ceramic insulators ...

Ceramic Electrical Insulating Materials

Journal of the American Ceramic Society, 1958
During the past 30 years, the principal ceramic insulating materials have been the electrical porcelains, the steatites, and the high alumina bodies. The compositions, the structures, and the properties of these materials are discussed. Other porcelains and insulating compositions, containing as their principal crystalline phases mullite, zircon ...
