REMOVAL OF ORGANIC ACID BASED BINDERS FROM POWDER METALLURGY COMPACTS

摘要

Organic acid-based binders are efficiently removed from powder metallurgy compacts, such as tantalum capacitor anode bodies, by immersion in a heated aqueous alkanolamine solution followed by rinsing in warm water. This method results in lower residual carbon and oxygen levels than are found with thermal binder removal methods.
