NanoArc™ - A New Physical Vapor Synthesis Process

Keywords:
nanoparticles, NanoArc, mixed metal oxides

Abstract:
Nanophase Technologies Corporation developed a new physical vapor synthesis process to manufacture nanoparticles - NanoArc™. The NanoArc™ process was developed in response to specific customer feedback requesting single nanocrystals with extremely chemically active surfaces. Concept feasibility was demonstrated and the process was scaled to produce commercial quantities of nanoparticles within 18 months. The NanoArc™ process is based on an “active plasma” technology and produces nanoparticle surfaces engineered to have high zeta potentials when dispersed in water. NanoArc™ nanoparticles are dense, discrete crystals with a composition palette that includes novel mixed metal oxides that are thermally stable solid solutions. The nanoparticles may be dispersed as primary crystallites which permit stable dispersions to be commercially manufactured. The particle size distribution may then be tailored to achieve specific application requirements. The process will be described. Novel new nanomaterials from the process will be described with specific attention given to differentiating characteristics which enable targeted applications – including polishing, catalysis, and abrasion resistance.
