[½»Á÷] ¡¾ÌÖÂÛ¡¿A question about agglomerate of magnetite nanoparticles

Magnetite particles(40-50nm derived from the Scherrer formula) was obtained by hydrothermal method in my experiment. Generally they tend to form agglomerates whose size maybe in micro-meter range. Then the product was dried at 50¡æ in an oven(not vacuum) for hours. The question is if magnetite nanoparticles can be oxidized during the drying process(not vacuum) or my product itself actually is micro-meter size.

It tends to be oxided by the O2 in the air and the agglomeration may be for the fundamental magnegic properties.

¡°the agglomeration may be for the fundamental magnegic properties¡± means the magnetic power among the particles can cause the agglomeration phenomena.
