摘要:
A process for the preparation of carbon protected superparamagnetic or magnetic nanospheres is claimed which comprises the steps:(A) coating FexOy particles with an organic polymer,(B) coating the product obtained in step (A) with silica,(C) subjecting the product of step (B) to pyrolysis conditions, and(D) removing silica.According to present process, structurally stable carbon protected magnetic nanospheres were obtained, which can be dispersed in various solvents like water, EtOH, toluene, etc.
