Abstract

This study delves into the effects of Al3+ doping on the microstructure and electrical properties of Li0.05Ni0.95O linear ceramic resistors, crucial for pulsed power applications. The research reveals that Al3+ doping leads to the formation of a solid solution, causing lattice expansion and influencing grain size. Notably, the Li0.05Ni0.94Al0.01O ceramic exhibits optimal properties with a resistivity of 2.86 Ω·cm, a resistance temperature coefficient of 7.2×10−3°C−1, and a nonlinear coefficient of 1.025. The study also highlights the fast energy transmission speed (t0.9<100ns) and no discharge delay in these ceramics, demonstrating their high potential for pulsed power systems. The findings underscore the significance of Al3+ doping in enhancing the performance of Li0.05Ni0.95O-based linear ceramic resistors, making them suitable for high-energy pulsed applications.
