Application of Molten Salt Method in Hercynite Composite Powder Synthesis at Elevated Temperature

Abstract:

With molten salt method, a series of the hercynite powders were prepared using FeCl₂·4H₂O, active alumina and iron powder as raw material and KCl molten salt as reaction medium. The phase composition and micro-morphology were studied by techniques of XRD and SEM. The results showed that a high purity hercynite-alumina powder can be synthesized by molten salt synthesis method after heat treatment at 1000 °C in reducing atmosphere, the main phases were hercynite and α-Al₂O₃, and the increasing iron powder content can raise hercynite production quantity with developed crystal grain, the grain size was increased from 6μm to 10μm.
