I have worked in electronics almost 50 years ago but I have never seen a tube of heat sink compound that contained beryllium oxide and never saw an advert for any either.

I briefly worked in one factory where they assembled power supplies that contained a power transistor insulated by an anodised sheet of aluminium. It was a common belief among the assembly workers that the sheet contained poisonous beryllium because of its grey color.

I am wg48 but not on my usual pc hence the temp handle.
Thank goodness for Fleming and the fungi.

I don't know who invented mRNA vaccines but they should get a fancy medal and I hope they made a shed load of money from it.

Beryllium (or maybe beryllium salts) is in the tip of some magnetrons from microwaves, where the microwaves are emitted.
I have heard that if the tip is damaged one should be careful, especially if there is dust or fine material from the damaged tip.
Maybe they have stopped using beryllium in magnetrons now but im not sure.
As a side note, i have a beryllium piece about 7 or 8 grams in my element collection.
I will not lick it.

I have a gram of Be spheres in an ampoule in my element collection and also a small 3 gram rod sealed in plastic. I do not foresee a reason to open either one. To me, Be is neither interesting nor desirable. I am sure I can handle it safely but the risks far outweigh the rewards because the rewards are so low.
