Solid atomization technology and process of molten metal and alloy

A novel solid atomization technology has been developed with a high-velocity gas jet stream containing solid salt particles as the atomization medium. Metal and alloy powders with a finer particle size, a narrower size distribution and a higher cooling rate than those of the conventional gas atomization technology have been produced by this technology. The affecting factors of the particle size of as-prepared metallic powders have been analyzed, especially the influence of the state of NaCl particles.
