Hi, does anyone need small (ie <10g) quantities of the following?

Yttrium oxide (Y2O3) have up to 100g
Titanium dioxide (TiO2)
Strontium carbonate (SrCO3)
Tantalum foil, 0.2mm EDIT: SOLD
Copper oxide (CuO2), have up to 200g
Indium metal as shot, up to 50g
Bismuth needles, up to 100g
BaTiO3 EL dielectric in sample container, not sure how much left..

EDIT: I also have maybe 50 large area germanium TO-3 PNP power transistors, if anyone wants them for photodetectors, low voltage amplifiers or similar.

Also have a few other random bits such as lead sheet, and also some
assorted small pieces of tin, pure copper wire and zinc.

I was hoping to use some of them for HTSC experiments but still haven't managed to source all the other stuff needed, maybe someone has a use?

Will put these in screw top containers, have a few of these spare.

Kind regards, -A

Hi Conundrum
Do you still have some KI or pure iodine?

I've got some "Mercurochrome", which is an iodine containing antiseptic.

Not sure how much iodine there is, but I've also got some recrystallised KCI/NaCI
