“…It is well-known in “dynamic” Ag/AgO/Pd resistor pastes that during cooling from 850 °C, oxidation/reduction processes occur [57,58,59]. This behavior can also be seen, when heating up AgPd electrodes [60]. The oxidation/reduction process start at 450 °C and are finished at 700 °C.…”

This paper examines the influence of a short-term thermal treatment of aerosol deposited negative temperature coefficient (NTC) thermistor films on the NTCR characteristics and their long-term stability with different electrode materials. An aerosol deposition of a spinel-based NiMn2O4 powder on alumina substrates with screen-printed AgPd and Au interdigital electrode structures was performed. The manufactured components of the typical size of 1206 were tempered in a moderate temperature range of 200 °C to 800 °C and aged for 1000 h at 125 °C in air. Based on R-T measurements in a high-precision silicone oil thermostat bath and high temperature XRD analyses, the influence of the thermal treatment was analyzed and discussed. A 60-min tempering at 400 °C proved to be optimal, as both the NTCR parameters and their ageing stability could be significantly improved. The findings are explained.

“…Thick lm resistors (TFRs) are one kind of thick lm component which has been applied extensively in hybrid circuits for power conversion, current limiting, voltage division, etc. [1][2][3]. TFRs can be formed by screen-printing the paste onto a substrate, followed by drying and ring in a belt furnace [4].…”

In order to explore an economical functional phase alternative material for thick lm resistors, the crystal structure, microstructure, and electrical properties of (1-x)LSCN + xLCNZ (x = 0.0-1.0) composite ceramics were studied through solid-state reaction experiments. The composite ceramics were characterized by xray diffraction, scanning electron microscopy, energy dispersive x-ray spectroscopy, and DC four-probe method. Results suggested that the main phases of LSCN and LCNZ were formed, along with a small part of impurity phases. The addition of LCNZ to LSCN decreased the electrical conductivity and changed the TCR from positive to negative. Zero TCR could be achieved around 0.6 < x < 0.8 and relatively low absolute TCR values could be obtained for the samples of 0.4 ≤ x ≤ 0.8. The ceramic of 0.6LSCN + 0.4LCNZ showed the optimal performances of conductivity = 1923 S/cm, TCR = 379.54 ppm/℃, and relative density = 95.05%.
