Nanosized Powders

Synthesis and Sintering of Nanosized Powders

By studying the densification and grain growth of nanosized powders during sintering, we have taken on the challenge of controlling grain growth during sintering of nano powders. The results have led to new insights and new processing techniques. We use two methods to make nano powders – a chemical vapor synthesis (CVS) process and a unique planetary high energy milling mechanochemcial synthesis technology. Additionally, a rapid-heating ultrahigh pressure (~1 GPa) hot-consolidation process has been developed. Hardmetals (WC-Co) and tungsten metal alloys based on nanosized powders have been produced.
