High-throughput powder synthesis system

United States Patent Application

View the Complete Application at the US Patent & Trademark Office
The powder synthesis system integrates "on-the-fly" precursor formulation and delivery, control of carrier gas flow rate and temperatures of a multi-zone reactor (to control time-temperature history of the particles in the reactor), with rapid filtering/collection equipment into a powder synthesis process that is representative of actual manufacturing time-temperature conditions. A control system provides automatic operation and data acquisition, while requiring minimal operator involvement. The system includes a delivery stage, a production stage, and a collection stage. The collection stage uses a camera style filter apparatus to collect the powder with minimal loss and isolates each sample to prevent contamination.
