Nanopowders are powders consisting of nanoparticles: particles with all dimensions less than 100nm. They are used in a variety of material fabrication processes, and many of our materials are available in this form. Nanoparticles can exhibit a variety of morphologies, including spheres, rods, fibers, cups, and stars. Nanoparticles can even be porous, as in the case of mesoporous silica nanoparticles. Materials sold as nanopowders typically contain particles with some degree of variation in morphology or size while still falling within the 1-100nm range. Nanoparticles with specific, uniform morphologies are often sold under a name that characterizes this morphology, and single-crystal nanomaterials are typically referred to as nanocrystals.ATT is capable of producing most compounds, metals, and alloys in the submicron and nanopowder range and atomized metallic powders in sizes as low as -325 mesh to ultrafine particle.
