Effect of Yttria Additions on the Electrical Conductivity of SHS Nitride Ceramics

Inorganic Materials Aims and scope

Abstract

The electrical resistivity of TiB2–AlN–BN ceramics with Y2O3 additions was measured between 300 and 1300 K as a function of the Y2O3 content of the starting mixture. The resistivity of the ceramics was found to exhibit anomalous, hysteretic behavior in a wide temperature range. This behavior is tentatively attributed to the metastability of percolation processes in the multicomponent conductive ceramics.
