What exactly is this and what is in it?

If you are going to sell boards I recommend checking with your buyer before removing anything that is soldered on to a board. Most will devalue boards when material is removed that is not in a socket.

As far as processing mlcc's yourself it is a bit involved since most are a combination of two metals. The most common are made of silver/palladium. Older ones pre 1992 can be silver/platinum or gold/platinum. To refine them you are dealing with very dangerous acids in addition to waste solutions which must be properly treated before disposing. I also would not recommend refining mlcc's unles you have a few pounds to make it worth the money you are going to invest in time, chemicals, equipment and studying to learn how to do it.

If you do refine them yourself you should know that palladium and platinum have very high melting temps. Platinum melts at 3220* F and palladium melts at 2831* F. Temps which are not easily reached with a commmon torch. As a matter of fact it is recommended that a hydrogen/oxy torch be used as one way to melt platinum. Another is the use of argon which can be costly in itself.



If you are not prepared to put in the time and money to do it properly then you should look for a buyer for mlcc'c, sell on ebay, sell to someone who can process them or have them toll refined.
