SPHERICAL PARTICLES HAVING NANOMETER SIZE, CRYSTALLINE STRUCTURE, AND GOOD SPHERICITY AND METHOD FOR PRODUCING

摘要

There is provided nanometer-size spherical particles. The particles of the present invention are made of at least one selected from the group consisting of a metal, an alloy, and a metal compound. The particles include one or both of a polycrystalline region and a single-crystalline region. The particles have a particle size of less than 1 μm; and a sphericity of −10% to +10%.
