Application of high magnetic fields in inorganic materials processing

Abstract

Application of high magnetic fields in materials processing has started. A high magnetic field enhances not only a Lorentz force in a weak electric current but also a magnetization force in non-magnetic materials. The main results obtained from the application of a high magnetic field to the processing of several materials is reviewed. These include the alignment of particles in a composite coating as an example of a Lorentz force and the separation of inclusions in a molten metal for mass transport using magnetic force. Orientation of crystals of non-magnetic materials using magnetization force is mentioned. The orientation was conducted in such processes as electro-deposition, vapour-deposition, solidification, baking, slip-casting and precipitation.
