Used in a variety of electronic applications as well as powder metallurgy applications, micron-sized metal powders are generated with a number of different techniques. One of the most common techniques is ultrasonic spray pyrolysis. Spray pyrolysis is a rapid, simple method that requires fewer steps in comparison to other atomization techniques. It allows for continuous processing and it is a process that allows for a quick and easy scale-up. Finding a better cosolvent for the precursor solution was the most recent objective in the research involving spray pyrolysis of pure metal particles and is what will be discussed for the bulk of this report.
Primarily, cosolvents with low health hazards, high production rates and those that make solid, dense particles were considered. This report will elaborate on how new cosolvents were evaluated and selected and what the future plans of the lab group are.
