摘要

以甘氨酸为燃料，经800℃煅烧，采用溶胶-凝胶燃烧法制备纳米晶锰镍矿(NiMn $_{2} O_{4}$)。x射线衍射(XRD)分析证实形成了晶粒尺寸为54.5 nm的纯立方尖晶石结构。所得锰镍粉的扫描电镜形貌为多孔纳米晶。在20-50℃的温度范围内，得到的锰镍粉作为糊状，在100℃下干燥的物质常数(B)为4812 K，证实了在柔性温度传感器中的潜在应用。

Nanocrystalline Nickel Manganite Synthesis by Sol-Gel Combustion for Flexible Temperature Sensors

Nanocrystalline nickel manganite (NiMn $_{2} O_{4}$) was obtained by sol-gel combustion using glycine as fuel, followed by calcination at 800°C. X-ray diffraction (XRD) analysis confirmed the formation of a pure cubic spinel structure with a crystallite size of 54.5 nm. Scanning electron microscopy (SEM) of the obtained nickel manganite powder showed porous nanocrystalline morphology. The material constant (B) of the obtained nickel manganite powder applied as paste and dried at 100°C was determined as 4812 K in the temperature range 20-50°C, confirming potential application in flexible temperature sensors.
