Learn MoreOne often overlooked source for the precious metal Palladium is the monolithic ceramic capacitors that reside on printed circuit boards. Am e-scrap recycler who collects a large quantity of these capacitors could send them to a processor or extract the metal in a home lab.
Most e-scrap digital electronic printed circuit boards contain trace amounts of Palladium in monolithic ceramic capacitors but this Palladium is possibly the most overlooked e-scrap recycler resource. A monolithic ceramic capacitor contains Palladium or a mix of Silver and Palladium.
C 2.9.1 Construction The capacitors consist, as the name tells us, of some kind of ceramic. The manufacturing process starts with a finely grounded ceramic powder mixed to an emulsion of solvents and resin binders.
Two alternatives exist for the recycler to take advantage of the Palladium content of monolithic ceramic capacitors. The first alternative comprises selling e-scrap circuit boards to board processors or arranging a sort of assay process. The second alternative is for the recycler to process the circuit boards.
The most common design of a ceramic capacitor is the multi layer construction where the capacitor elements are stacked as shown in Figure C2-70, so called MLCC (Multi Layer Ceramic Capacitor). The number of layers has to be limited for reasons of the manufacturing technique. The upper limit amounts at present to over 1000.
These capacitors are quite small but exist on most digital circuit boards disposed of as e-scrap, including memory sticks. Monolithic ceramic capacitors may be identified by a light brown or tan color but they may be other colors as well. The photo below, courtesy of Jeff Keyser (2011), shows a monolithic capacitor in a microscopic view.
