Most of ceramic materials are dielectric materials having very low electric conductivity but supporting electrostatic field. The electrical conductivities differ by a factor as large as 10 12 10 21 between metallic and ceramic materials. Electrical conductivity is ability of material to conduct electric current. Ceramic products used as electrical insulators include spark plugs hermetic.

This book discusses the mechanical properties of ceramics and aims to provide both a solid background for undergraduate students as well as serving as a text to bring practicing engineers up to date with the latest developments in this topic so they can use and apply these to their actual engineering work. Ceramics are generally bad conductors. Despite of very low electrical conductivity of most of the ceramic materials there are ceramics possessing superconductivity properties near to zero electric resistivity. Vuong and hồ thị thanh hoa journal journal of materials science and chemical.

The phase structure microstructure and electrical properties of the ceramics were investigated. Some ceramics cubic boron nitride are good conductors of electricity. Ceramics are intermediate in density. But fine ceramics and porcelain are insulators that do not conduct electricity.

Lanthanum yttrium barium copper oxide ceramic may be superconducting at temperature as high as 138 k. Xrd investigation reveals that the.
