Study on Preparation of the Precursor of Sm2Fe17 Alloy by Oxalate Co-Precipitation

Article Preview

Abstract:

In the oxalate system, some factors of pH values, reactant concentration, feeding method and reaction temperature affecting the grain size and morphology of the precursor of Sm2Fe17 alloy by co-precipitation were investigated. By means of comprehensive experimental and XRD and SEM analysis, the optimum conditions for preparing the precursor of Sm2Fe17 alloy by co-precipitation were obtained and it laid a sound foundation for the subsequent preparation of high-performance magnetic material.
