The preparation of MnZn-ferrite nanoparticles in a water/CTAB, 1-butanol/1-hexanol reverse microemulsion

摘要

Manganese zinc ferrite nanoparticles were prepared using a precipitation in reverse microemulsion system consisting of hexadecyltrimethyl ammonium bromide (CTAB) as a surfactant, 1-butanol as a co-surfactant, 1-hexanol as an oil phase and an aqueous solution of metal sulfates. Tetramethyl ammonium hydroxide (TMAH) served as the precipitating agent. The influence of the microemulsion's composition on the nature of the spinel product was studied. The synthesized nanoparticles were characterized using transmission electron microscopy (TEM), X-ray dif-fractometry (XRD), specific surface area (BET) and magnetometry.
