Abstract
Here, NiMn2O4 and NiZn0.2Mn1.8O4 nanocrystalline ceramic powders are fabricated, characterized, and compared for thermistor applications. Solution route was used to synthesize the materials. The NiMn2O4 is a spinel single crystal material with the average crystallite size 26.82 nm and a particle size less than 1 μm and has uniform morphology. The EDS results confirmed the composition of NiMn2O4 that consisted of Ni, Mn, and O2 only. The average crystallite size of NiZn0.2Mn1.8O4 is 37.48 nm and the particle size is less than 0.5 μm. There has been observed some agglomeration formation due to high calcination temperature. The β-value of NiMn2O4 is larger than NiZn0.2Mn1.8O4, hence thermistors constructed from NiMn2O4 are more stable and applicable as NTCR thermistor powder.
