In this research work, the capacitance, inductance, impedance and dielectric constant of novel self-generated Ti3AlC2 and Ti4AlN3 MAX phase reinforced boron composites (Ti4AlB2C and Ti4AlB2N) are studied using precision impedance analyzer. Before that, the synthesized composites were sintered at different temperatures from 950 °C to 1325 °C. In the analysis, the positive impedance is found for both the compounds. But the negative capacitance, inductance and dielectric constant are significant in all the cases, which can improve the electrical conductivity of interconnects in semiconductor circuits and lower resistive losses and ultimately can improve over all device performances.
