Non-metallic Particles Manipulation in Liquid Metals During Electromagnetic Processing

Zhi Sun

Research in manipulation of non-metallic particles in a liquid metal by using an electromagnetic (EM) field is promoted by both the requirement of more efficient materials design and the development of cost-effective electromagnetic apparatus. The particles of sub/micrometer sizes can be agglomorated, segregated, aligned and/ or removed by applying a suitable EM field during liquid metal processing. The effciency and applicability depends highly on the nature of the particles and the difference from the liquid metal matrix. In the present paper, the fundaments/physics of non-metallic particles manipulation by EM processing are discussed and some potential application possiblities in industry are proposed.
