Nano-structured, high surface area metal or ceramic powders have a growing interest within many markets including energy conversion, catalysts, and electronic materials. Manufacturing high purity metal powders at an industrial scale is a challenge due to trace impurities impacting powder performance. In particular, oxygen, nitrogen, and carbon impurities can adversely affect the physical and chemical properties of refractory metals such as titanium, tantalum, tungsten, and niobium. Here we present a nanoscale alloy powder produced using a scalable sodium synthesis technology. Primary particle size and aggregate morphology of the resulting powder can be optimized for the given application by adjusting process parameters including optional metal or gas doping. In one such application, we adapt the powder for capacitor testing with promising electrical performance. We are also actively working with other industry partners to develop new applications for nanostructured alloy powders with tunable surface properties and different compositions.
