Fine powders of aluminate, ferrite, and chromite spinels were successfully produced by a novel Counter-Flow Liquid Injection Plasma Synthesis (CF LIPS) method using a DC plasma jet. CF LIPS has been demonstrated to be an excellent method to produce fine ceramic powders with a narrow particle size distribution. The spinels produced by this techniques, both magnetic and non-magnetic, have a very similar particle size distribution. The powders produced were spherical, non-agglomerating and dispersable with average sizes of 1 μm.
