Sumitomo Metal Mining developed this ultrafine nickel powder—less than 0.1 microns—using proprietary wet synthesis technology refined over many years. Despite their fine size, the particles show a uniform size distribution and excellent dispersibility. The powder also has low impurity levels, with few of the organic-derived impurities common in wet-process products, making it suitable for a range of electronic components.

These nickel powders are spherical with smooth surfaces and contain few agglomerated particles or consolidated particles. These properties make the powders well suited to a range of functional inks, slurries, and pastes. Potential applications include:

• Various electrode materials (conductive paste)
• Catalysts for chemical reactions (hydrocarbon reforming, hydrogenation reactions)
• Magnetic materials (data storage, magnetic sensors)
• Electromagnetic shielding materials
• Sintering materials

Wet synthesis is a particle-synthesis process that uses chemical reactions in water or other solutions. The process produces a wide range of materials, including nanoparticles, metal complexes, and metal oxides. Sumitomo Metal Mining makes its ultrafine nickel powder by using wet synthesis, which gives the powder a uniform distribution of particle sizes. For more on the process, see our column "Crystallization Used for Metal Powder Manufacturing" below.
