| Popis: | Two types of dextran iron-oxide complexes (ATDM and CMDM), magnetic fluid applicable to the contrast agent of magnetic resonance imaging of living body, have been synthesized without surfactant. We have measured temperature dependances of magnetization and X-ray diffraction of ATDM, CMDM and also magnetite fine-particles as a reference substance in atmospheres of air and helium up to 840°C. The results are discussed in view of the reaction of magnetite core with the surrounding gas and products formed by thermal decomposition of the dextran molecules which is directly bonded to magnetite core of the complexes. |
