Maybe someone can help me out here. I have an electronics technician friend who keeps going on about all the older ceramic cpu's are beryllium oxide based whether they are colored white or purple. I haven't heard of this anywhere and believe he is dead wrong. Anyone heard anything like this?
Hey I was just surfing and checked this out and here is a cut of what I found:
Accordingly, beryllium oxide (BeO) is not only hazardous, but also found in significant quantity in e-waste items. It is applied as filter in some interface materials (e.g., thermal grease used on heat sinks for computer processing units, CPUs and power transistors), magnetrons, x-ray transparent windows, heat transfer fins in vacuum tubes and glass lasers.
This was copied from here: Recyclability Potentials of Beryllium Oxide from E-waste Items in Nigeria
This is probably only a little head ways but it looks like it is in the "thermal grease" that was used between the heat sinks and processors. Hope that helps clarify a little bit. But I'm sure there might be other uses for it.
****, I guess i need to stop wiping that grease off with my fingers. This might explain my twitch! lolQuote:

Or you can treat them with Lye, it does a great job stripping off soldering masks, grease, and other organic material. You just need to take the safety precautions associated with working with Lye, I wouldn't suggest anyone doing so without first reading about the safety issues. But so long as you are careful, it's a fairly common practice to use Lye to strip off things you don't want to be touching.
