| Abstract Scope |
Traditional silicon based electronic sensors cannot withstand the conditions found in advanced nuclear reactors and other high temperature environments. A variety of new electronic materials are needed for functional and robust high temperature sensors. Electro-conductive aluminum nitride (AlN) has been worked on for a few decades, but the previously achieved conductivity values are not high enough for many applications. In this work, we study the effect of the combination of conductive carbides and conductive particles on the microstructure and electrical conductivity of AlN synthesized by ball milling and spark plasma sintering. The interaction between the particles and carbides is elucidated by electron microscopy. |
