magnetic product
2.his note reports the solid state redox reaction of [Fe(phen)3](ClO4)3·H2O with sodium sulfite at room temperature. It has been found out that the reaction is complete, and the reaction velocity is fast. Mossbauer spectrometry, clemental analysis, XRD, FTIR and Magnetic susceptibility were used to characterize the solid state product.
3.moreover, the structural analysis of the magnetic bearing design process is also discussed. Based on these studies, by considering the configuration and constraints of axial magnetic bearings for a flywheel energy storage system, the authors put forward a rational sequence for designing this product better than the conventional trial|and|error method, which establishes the foundation of the performance sy stem of magnetic bearings.
4.The process of separating impregnated iron from potash feldspar has been studied in alkaline solution by JC-COP activator and enhanced leaching agent after reelection and magnetic separation, as a result, the content of Fe2O3 in potash feldspar product decreases from 4.05% to 0.1%~0.2%, and its color becomes white from pink, its quality is high, and the economic benefi t will be improved.
5.The study of the compositions, processes and properties on Ni-Mo-Nb-Fe alloy u-sing the high induce-magnetic experience formula concluded by Enoch and Rassmman for Fe-Ni alloy is described in this article. The finished product strips with excellent syathetical physical performance and high quality to meet the requirements of the magnetic head manufacture-line imported are obtained.
7.A new commerical oxidation process of cyclohexanol to cyclohexane-1, 2-dione-hemihydrate by nitric acid and some affecting factors are discussed. The structure of the product is determined by infrared spectrometer(IR), Nuclear magnetic resonance(HNMR). Ultimatenaly asis and melting point testing, Some new methods, for example, putting in initiator, changing the concentration of reactants, washing and separating the product with hot water instead of ether, are first used in this process.
