Rare-Earth Powder Eases Molding of Magnets.Magnequench Inc., Anderson, Ind., has developed a new isotropic Refers to properties that do not differ no matter which direction is measured. For example, an isotropic antenna radiates almost the same power in all directions. In practice, antennas cannot be 100% isotropic. magnetic material for use in injection molded magnet compounds. MQP-S-9-8 is a neodymium-iron-boron (NdFeB) rare-earth magnetic alloy that comes in a spherical spher·i·cal adj. Having the shape of or approximating a sphere; globular. powder form. Particle size Particle size, also called grain size, refers to the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied to other granular materials. is 50 microns, or 33% of the size of current NdFeB powders. It reportedly provides improved flowability when used as filler fill·er 1 n. One that fills, as: a. Something added to augment weight or size or fill space. b. A composition, especially a semisolid that hardens on drying, used to fill pores, cracks, or holes in wood, plaster, in a polymer matrix. It thereby improves molding of complex and sharply defined parts and also helps extend tool and machine life. Thermal stability, corrosion resistance, and magnetic-flux uniformity of moldings are also said to be improved by the smaller particles. |
