Study on the stability and viscosity of Fe3O4 nano-particles vegetable insulating oils

Vegetable insulating oils are fire-resistant and environment-friendly liquid dielectrics, so it gets wide attention of scholars both at home and abroad. The paper used pyrolysis method preparation the Fe₃O₄ nano-particles vegetable insulating oil with narrow particle size distribution and high dispersion. The paper also studied on the influence of nano-particles insulating vegetable oil stability and viscosity, with join or not the different types surfactants (CTAB, SDS, PVP) in the preparation of nanometer particle. The results show that, the Fe₃O₄ nano-particles vegetable insulating oil has good stability, and the viscosity of Fe₃O₄ nano-particles insulating oil has significant effect with different types and concentration of surfactant.
