6K develops microwave plasma technology for producing battery materials and engineered powders from metals, recycled feedstocks and other materials.
Plasma processing for critical materials
6K develops UniMelt, a microwave plasma platform that transforms feedstocks into engineered materials. Its work spans battery chemicals and powders used in advanced manufacturing.
The process is designed to replace longer industrial production routes and accommodate a range of metals and other materials. Recycled metals, used batteries and existing powders can provide inputs for local material production.
Scaling industrial production
The company is based in North Andover, Massachusetts. Its development work connects material formulation with the production systems needed to manufacture those materials at industrial scale.
