Rare Earth Silicide Formation on Si Electrode in LiCl-KCl Melt to Establish a Novel Used Salt Treatment Process

When apatites and phosphorites are processed, up to 30% of rare earth metals are converted into wet-process phosphoric acid. Wet-process phosphoric acid from the phosphorite treatment process differs from apatite one by impurity composition, i.e. the iron content is by 3.5 times, and calcium is by 5.0 times more. The complex composition of the wet-process phosphoric acid from the phosphorite treatment process requires additional researches to select optimal ion exchangers and technological parameters of sorption. Various aspects of sorption have been studied to select the optimal ion exchangers and technological parameters, and technological modes for desorption of rare earth metals from a cation exchanger to obtain a concentrate of rare earth metals have been completed. The method enables to extract rare earth metals without changing the composition of commercial wet-process phosphoric acid directly in the production process of the enterprises engaged in the phosphorite treatment process.

Rare Earth La

The influences of the different content of Rare earth La on the corrosion resistance of AZ81 in the simulated human fluid were studied. In order to further improve the corrosion resistance, different heat treatment procedures were studied. Results showed that with the increase of content of rare earth La, the grain size was refined and the corrosion resistance increased. The corrosion resistance was improved after T6 heat treatment (solid solution+ aging). Microstructure analysis showed that β-phases were precipitated in the T6 heat treatment process. Those fine β phases acted as corrosion barrier and impeded the corrosion extending.
