Preparation of fe-50 wt.% co nanopowders by calcination and hydrogen reduction of nitrate powders... However, in case of the reduced powder at 350 degrees C, the M(s) and H(c) values are changed to 120.0...
Preparation of metallic iron powder from pyrite cinder by carbothermic reduction and magnetic separationThe reduction and magnetic separation procedure of pyrite cinder in the presence of a borax additive was performed for the preparation of reduced powder....
Niobium powder synthesized by calciothermic reduction of niobium hydroxide for use in capacitors... Sintered pellets of the metallic powder showed a higher capacitance (CV) than those of the simply reduced powder without pre-treatment, because the shrinkage during sintering was smaller....
Effect of rare earth y on properties of nanosized 90w-7ni-3fe composite powder fabricated by spray drying-hydrogen reduction... Phase composition, crystalline size, and particle morphology of the reduced powder have been measured by X-ray diffraction and scanning electron microscope (SEM)....
