Ceramic With High Electrical Conductivity

Alumina 94 97 demonstrates high electrical resistivity and strength and low dielectric loss.

Ceramic with high electrical conductivity.

Most ceramics resist the flow of electric current and for this reason ceramic materials such as porcelain have traditionally been made into electric insulators. Lanthanum yttrium barium copper oxide ceramic may be superconducting at temperature as high as 138 k. The first of these was. Some ceramics however are excellent conductors of electricity.

Despite of very low electrical conductivity of most of the ceramic materials there are ceramics possessing superconductivity properties near to zero electric resistivity. Most of these conductors are advanced ceramics modern materials whose properties are modified through precise control over their fabrication from powders into products. Most high tc ceramics are layered structures with two dimensional copper oxygen sheets along which superconduction takes place.
