Preparation method: high temperature pyrolysis method
Saturation magnetization: ~60 emu/g Fe
Dispersibility: oil-soluble, can be dispersed in (chloroform, n-hexane) solvents
Features: Compared with the co-precipitation method, it has stronger magnetism and more uniform size.
Note: The Fe concentration in the solution is 1 mg/mL, and the Fe concentration in the powder is unknown.
The TEM image is obtained from solution testing. Slightly larger particles may appear in powder testing. If you need to observe the morphology, it is recommended to purchase a solution.
Above 30nm, you can use a magnet to separate directly, and below 30nm, it is recommended to use a magnetic separation column for separation.
The dispersion effect of powder redispersion is worse than that of dispersion liquid. If you want good dispersion effect, please choose to purchase dispersion liquid.
