摘要: 本文用胶溶法合成了NiO纳米晶超微粒.初步探讨了合成的最佳实验条件.研究了不同灼烧温度及同一温度不同灼烧时间对NiO超微粒子微晶的晶化过程的影响.用X射线衍射、红外光谱、热重、差热、透射电镜研究了样品的性能.结果表明,用胶溶法制得的NiO纳米晶的粒度均小于6nm,属立方晶系,形状为球形.电导率随着温度的升高而迅速增大,是一个有应用前景的热敏材料.

Abstract: NiOnanocrystalline materials were prepared from NiCl2 and NaOHby the colloidal chemicai method.The most favourable experiment conditions for the preparation of NiOultrafine particles(UFP) were studied.XRD,IR,TG,DTAand TEMexaminations were used to characterize the samples.The spherical UFPparticle NiOis cubic crystal with an average diameter of 6.0 nm.

Key words: Nanocrystalline ultrafine particles, NiO, Colloidal chemical method
