  • Electrically conductive ceramics with oxides of Al, Cr, and Mg
    Patent number: 5656203
    Abstract: A conductive ceramic composition is disclosed which consists essentially of alumina, chromia, and magnesia, and is suitable for use as target electrodes in electrostatic fiber charging applications. Ceramics are disclosed which have exhibit volume resistivities of 10.sup.12 ohm-cm or less at 20.degree. C., and have excellent electrical stability and superior mechanical properties; and an electrostatic charging apparatus is disclosed which employs a ceramic electronic conductor having a volume resistivity of from about 1.times.10.sup.7 to 5.times.10.sup.10 ohm-cm and a hardness of at least 5 GPa.
