    Feb 16, 2018 Mg 3 Sb 2 compounds were synthesized via low-temperature solid-state reaction (SSR) and ball milling (BM), respectively, followed by spark plasma sintering (SPS) process. The effects of possible sintering pressure-induced orientation in the SPS process have been investigated in terms of the microstructure and thermoelectric transport properties. The results indicate that BM technique

    Jun 15, 2012 Jun 15, 2012 1. As the name suggests, the ball milling method consists of balls and a mill chamber. Therefore over all 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). 2. The powder of a material is taken inside the steel container. This powder will be made into nanosize using

    Apr 24, 2008 Ball-milling was carried out using zirconia grinding media in ethanol. Then the slurry was dried. In SSR processing, the dried mixture was calcined at 800–1050 C to prepare the aimed SrNb 2 O 6 powders. While in MSS processing, the dried mixture was mixed with KCl and calcined at 800 C to get SrNb 2 O 6 particle powders. For the synthesis of KSr 2 Nb 5 O 15 particle powders, only MSS

    For all nanocrystalline materials prepared by high-energy ball milling synthesis route, surface and interface contamination is a major concern. In particular, mechanical attributed contamination by the milling tools (Fe or WC) as well as ambient gas (trace impurities such as O 2 , N 2 in rare gases) can be problems for high-energy ball milling
