Hielscher - Ultrasound Technology

In the past few years nanomaterials have become integral components of products as diverse as sunscreens, electrically conductive coatings, and strong, lightweight plastic composites.

Today, large number of industries, from ceramics to cosmetics and pharmaceuticals, metals to paints, inks and coatings, electronics and semiconductors - rely on fine sized powders and materials to produce their products. The production and processing of these materials is a quickly progressing technology. Indeed, it is advancing rapidly and creating new possibilities for many industrial processes.

The goal of most powder-based processing has been smaller size and improving the uniformity of particles. New methods of powder production and synthesis are rapidly pushing the limit lower and lower. Particles of submicron sizes - so called nanoparticles - are now critical to advancements in numerous applications. Ultrafine powders are essential materials in the production of catalysts, coatings and films, conductive pastes, cosmetics, electromagnetic components, electronic devices, fire retardant materials, magnetic fluids, sintered and injection molded metals, ceramic composites, magnetic storage media, phosphors, pigments, polishing media, and toners.

Nanomaterials fall into three broad categories: metal oxides, nanoclays, and carbon nanotubes. Metal-oxide nanoparticles, include nanoscale zinc oxide, titanium oxide, iron oxide, cerium oxide and zirconium oxide, as well as mixed-metal compounds such as indium-tin oxide and zirconium and titanium, as well as mixed-metal compounds such as indium-tin oxide.

For many of these nanosize materials, Hielscher ultrasonic equipment is being used for the dispersing of the powder into liquids. In particular for the deagglomeration and for the break down of primary particles in sub-micron-range Hielscher ultrasonic equipment has proven to be very effective.
