One 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.
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.
Palladium content in ceramic capacitors is significantly higher than Pd content in primary ores from which it is extracted (on average < 10 g/t) [ 35 ], then using secondary Pd as feedstock reduces energy consumption in addition to conserving resources. Other PGMs like platinum and iridium are present only in trace amounts.
A ceramic capacitor chip Ceramic chips for surface mounting looks in principle like the one in Figure C2-74. MLCCs are by far the leading downsizing and miniaturization technology among passive components. Chart bellow is illustrating shift of the case size mix in MLCCs.
