The recent needs for safe and secure automobiles energy-saving appliances have increased the demand high-efficiency motors high-sensitivity sensors. While performance of these devices largely depends on intrinsic properties magnet materials used in devices, it is also important to improve flexibility order form them into complicated shapes durability usage high temperatures or severe environmen...

The alkali melting method was used to pretreat the specimens of Neodymium-iron-boron alloy, and inductively coupled plasma atomic emission spectrometer determine main element boron in NdFeB alloy. parameters instrument were optimized select best spectral line for determination boron, effect matrix overcome by adding Fe. has good precision accuracy, recoveries are range 99%∼101%, RSD less than 1...

NdFeB magnets are the most widely used rare earth permanent magnet materials at present. The increasing number of waste and their high content motivate a search for technologies to allow cost-effective environmental-friendly recycling. In this study, removal oxide inclusions from by supergravity technology was investigated separating conditions were optimized maximum removal. Under G = 800 t 15...

Neodymium (Nd) was continuously extracted from aqueous solutions by trioctylphosphine oxide (TOPO) dissolved in the ionic liquid 1-Butyl-3-methylimidazolium Bis (trifluoromethanesulfonyl)imide [C4mim][Tf2N] small channel contactors. Kinetic studies confirmed a 1:6 Nd:TOPO extraction mechanism at high initial Nd concentrations of 0.005 and 0.01 M 0.001 nitric acid phase. The continuous flow extr...
