Hybrid Gas Atomization for Powder Production

Towards an Expert System for Powder Production Processes : (I) the Atomization Process

The practical definition for the expert system, as a system simulating the expert methods and knowledge in dealing with or manipulating special tasks is presented. The application of such a system in powder technology is attempted. The main features of the proposed system design are documented. It constitutes, actually, another part of an effort towards building an expert system for powder tech...

Production of fine Nd-Fe-B alloy powder by pulsed plasma atomization

Extremely fine (<10 μm) Nd-Fe-B powder was generated by pulsed plasma atomization processing. The number average was just over 3 μm, as determined by computer-assisted scanning electron microscopy analysis of almost 3000 particles. Despite the fine particle size, alloys of stoichiometric Nd2Fe14B resulted in the properitectic formation of -Fe, deleteriously affecting the magnetic properties. N...

Production of Iron Disulfide Nanoparticles by Hydrothermal Process

In this research, a single-stage low-temperature hydrothermal synthesis route was successfully developed for preparation of Iron Disulfide. The prepared powder was characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). These analyses showed that nanoparticles were well crystallized, pyrite was the main product and the shape of crystals was nanorod. Also, the influences...
