Nanoparticles:Mild Dispersion

By Harry Way, NETZCH Fine Particle Technology |

    As the nanoparticle market continues to swell, expertise is surfacing about nanoparticle grinding and dispersion processes. A grinding solution (wet grinding with agitator bead mills) achieves the production of nanoparticles with an average fineness of 40–100 nanometers (nm). However, dispersion doesn’t always come as easily. Chemists and process engineers found that many dispersion processes can break down the primary particles, ruining the nanoparticles’ surface condition, crystal structure and overall chemistry, thereby rendering them ineffective. This article discusses grinding and dispersing of nanoparticles, as well as a new trend in wet grinding called mild dispersion that makes it possible to maintain the chemical integrity and structure of submicron particles, even through grinding and dispersion.   Grinding and dispersing The grinding mechanism for almost any material is more complicated than it initially appears. The first variable to consider is the material and its form. For example, in the ink and paint industry, raw materials start out at the desired particle size in powder form. The powder needs to be deagglomerated and dispersed into liquid. Although this sequence of steps technically…
