Comparative Experiment on the Erosion Resistance of NdFeN and NdFeB Flexible Bonded Magnets
The applications of NdFeB magnet is limited in a great degree because of the shortcoming of erosion and oxidation, although it has excellent magnetic properties. We have prepared flexible bondedExpand
Quantitative analysis for semi-finished products of barium hard ferrite by XRF
This paper introduces an analytical approach to determination of semi-finished barium hard ferrite with X-ray fluorescence spectrometry(XRF),Comparison was made between sample preparations of theExpand
Determination of Trace Silicon in High-purity Zinc by Butyl Alcohol Extraction Molybdenum Blue Spectrophotometry
At pH=1~ 1.5,yellow siliconmolybdate was formed,and then extracted by butyl alcohol from 0.5 mol/L of sulfuric acid medium.The yellow siliconmolybdate in the organic phase was reduced by stannousExpand
Surface Modification of Fe_3O_4 Ultrafine Particles by Coating SiO_2
Fe3O4 magnetic ultrafine particles were prepared by chemical-precipitiation method, and by subsequent acidizing the particles in sodium metasilicate solution, SiO2-coated particles were obtained. TheExpand
The Methods and Effects of Reducing Cr~(6+) Contents in Plastic-rubber Ferrite Magnetic Powder
On account of high Cr6+ content in domestic plastic-rubber ferrite powder and considering the characteristic of Cr6+ formation in the powder,experiments were performed on reducing the Cr6+ content byExpand
