Strategies for tailoring the properties of chemically precipitated ...

Fig. 1 represents the change in the concentration of solute metallic atoms in the precipitation process. The supersaturation builds up from A to B. Once the concentration of metal atoms reaches the critical supersaturation, S c, nucleation occurs (point B). It is typically a very rapid process (''burst'') followed by a rapid depletion of the solute atoms until their concentration decreases ...

physicalmethods Nanoshel a Nanotechnology Company

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 be made into nanosize using the ball milling technique.

Some of the techniques include stir casting, squeeze casting, friction stir processing (FSP) and high energy ball milling of mixed powders. High energy ball milling is one of the most popular techniques used for enhancing the distribution of the nanoparticles. However, high energy ball milling results in hardening of the mixed nanoceramicAlmatrix powders resulting in the formation of incompressible powder that is necessary during the compaction and sintering steps.
