Background

Nanophase Technologies is an industry-leading nanocrystalline materials innovator and manufacturer with an integrated family of nanomaterial technologies. The entire focus of Nanophase is nanotechnology, with two distinct and patented processes for the preparation and commercial manufacturing of nanopowder metal oxides i.e. Aluminum Oxide, Zinc Oxide, Cerium Oxide, Titanium Dioxide, and several others. Nanophase Technologies Corporation has developed a process, Discrete Particle Encapsulation, to coat the surface of its nanoparticles with a thin polymeric shell that enables compatibility of the particles with a wide variety of fluids, resins and polymers. Also, Nanophase has developed technology to permit the dispersion of its nanoparticles in water and a variety of polar and non-polar organic fluids. This allows Nanophase to supply concentrated, ready-to-use nanoparticle dispersions, eliminating the need for customers to disperse the nanoparticles themselves. Nanophase's family of integrated technologies economically produces nanocrystalline materials, and then nanoengineers those materials to fit a customer need.

Applications and Markets

Nanophase produces engineered nanomaterial products for a variety of diverse markets: personal care, sunscreens, abrasion-resistant applications, environmental catalysts, antimicrobial products, and a variety of ultra-fine polishing applications, including semiconductor wafers, hard disk drives, and optics. Various applications include wood preservation, anti-fouling and anti-microbial coatings, fuel cells, catalytic converters, UV-attenuation coatings, scratch resistant coatings, charge dissipating coatings, deodorant/antiperspirants, depilatory/shaving products, and others. In parallel, new markets and applications are constantly being developed.

Fuel Cells

It has been reported that the use of rare earth metal oxides has utility in various aspects of fuel cell design, but especially as components in electrodes and as low-temperature electrolytes in solid oxide fuel cells (SOFC).

NanoArc Ceria

NanoArc ceria and mixed rare earth metal oxides have shown promise in testing for such applications. Special formulations of mixed rare earth metal oxides can be commercially manufactured according to development partner or customer requirements, an example of which is a range of ceria samaria nanomaterials made specifically for a fuel cell application. Nanophase has also developed patent pending technology for applying these and other nanoparticle coatings using standard high-velocity oxy-fuel (HVOF) thermal spray equipment.
