Stoichiometric mixtures of ZnS + Al and ZnS + Mg were milled for different times in a planetary ball mill. The XRD traces of the asmilled samples showed the presence of zinc, MgZn 2, and MgS after 30min milling in the ZnS–Mg system.
Solid solutions of TiB2–ZrB2 and TiB2–HfB2 were obtained under an inert atmosphere by highenergy ballmilling mixtures of Ti/Zr/B and Ti/Hf/B, respectively.
synthesis of ZnS only formation of sphalerite. It can be presupposed that the mechanochemical synthesis of ZnS nanoparticles occurs through an intermediate stage where both forms are present. A more understanding about the mechanism of these transitions is presupposed by the study of the mechanochemical synthesis kinetics.
The ball milling method: A ball mill contains a stainless steel container and many small iron, hardened steel, silicon carbide, or tungsten carbide balls are made to rotate inside a mill (drum). The powder of a material is taken inside the steel container. This powder will .
Abstract. Organic sulfur in high sulfur petroleum coke was treated as the S source for synthesis of ZnS photocatalyst. Experimental results showed that with ball milling and subsequent heating treatment, ZnS compound could be successfully synthesized and showed considerable photocatalysis activity for decomposing industrial pollutants.
