| titleOfInvention | A kind of nano vanadium carbide ferrofluid and preparation method thereof |
| abstract | A kind of nano vanadium carbide ferrofluid and preparation method thereof, adopt particle diameter be the high-energy ball milling nano-magnetic vanadium carbide of 30 ~ 60nm as the magnetic particle in magnetic fluid, adopt aqueous solution dosing method to prepare presoma, barium oxide direct carborization prepares nano vanadium carbide; After high-energy ball milling, obtained nano-magnetic vanadium carbide, then by pre-dispersed in base fluid for nano-magnetic vanadium carbide particulate, obtains nano vanadium carbide ferrofluid after surface modification.Nano vanadium carbide particle diameter prepared by the present invention is 30 ~ 60nm, and reunite and not serious, after high-energy ball milling, there is ferromagnetism, saturation magnetization is 48.02emu/g, saturation magnetic field intensity 4000Oe, after surface modification, nano-magnetic vanadium carbide particulate has well dispersed and stability in base fluid, magnetic fluid saturation magnetization 6.87emu/g, can be applicable to magnet fluid sealing, Used in Boundary Lubrication of Magnetic Fluids and magnetic fluid damping etc., and under can be applicable to the special environment such as strong oxidizing property. |
