They contain mlcc's non magnetic, also should contain Palladium and silver. I never processed palladium and not sure I want to. Anyone who wants to refine them for me?
Fine wire wound or etched thin line resistive temperature transducers (often 100 ohms at room temperature) are typically platinum. The amount of metal on the vapour film ones is trivial but the wire wound ones can have reasonable amounts. The thicker wire devices that carry more current when in use are typically encapsulated in bososilicate glass and the wire is ribbon shaped. The flat rectangular ones using a wire are typically wrapped over a ceramic (aluminide) wafer, or a fiberglass and resin board. I am sure people here would have a proper method for each. A guess by me would be HF acid for the borosilicate glass pack, pyrolysis followed by mechanical for ceramic, and ozone ashing for fiberglass and resin (leaving fiberglass and platinum).They contain mlcc's non magnetic, also should contain Palladium and silver.
