Abstract

The electrical behavior of borides is important as they are envisaged as potential material for high-temperature contacts and interconnect materials along with their stability and higher wear resistance than many metallic or composite interconnects and contacts. Though single-phase borides' electrical behaviors are reported at room temperature, the composites of borides have been studied very little. The dispersion of borides of Ti/Zr/Ta in alumina becomes a good conductor material from an insulator, besides being a robust material against abrasion and corrosion in a harsh environment. This electrical behavior in the composite is due to the higher electrical and thermal conductivity of these borides and can be potentially used for many applications. The present manuscript discusses the effect of alumina diluent during the synthesis of Al2O3-Ti/ZrB2 composite on crystallographic phase, microstructure, electrical behavior, and structure–property correlation of the composite. The alumina-boride-based composites were developed by SHS dynamic compaction process with alumina diluents.
