TL;DR: In this paper, an acid leaching and solvent extraction system has been developed and optimized to extract scandium from wolframite residue, with the result that the scandiam oxide content in the resultant sccandium hydroxide can reach 70-78 percent.

TL;DR: In this paper, the authors demonstrate that the control of pH has a significant effect on the ability of precursors to crystallize and hence plays an important role in determining the formation and fraction of various crystalline phases in the resulting yttria-stabilized zirconia powder.

TL;DR: The 31 P MAS NMR spectra were measured and analyzed for the two phosphate glasses that contain distinct metals (i.e., In or Ba), different amounts of PbO, and the same content of P 2 O 5 and Al 2 O 3 as discussed by the authors.

TL;DR: Extraction chromatography by which 99.99% pure scandium oxide can be prepared from starting material containing about 70% scandiam oxide has been developed by taking advantage of some peculiar properties of complexation and extraction chemistry.

TL;DR: In this paper, a wet chemical process has been developed for the preparation of a lead-indium phosphate compound, and the effect of incorporation of aluminum into the compound on the thermal properties of the resulting glass is reported.
