99,9% Hafnium van Arkel der Boer crystal bar

Got some more interesting items - this one I especially love.

Around 50mm long, 9mm in diameter and weighs almost 35 grams. Would recommend to anyone wondering what element to get.

Also, it's my first actual hafnium sample! Before that, I only had a gram of turnings and a plasma cutter nozzle assembly.

Hi!

Here are some of my newest purchases. Pretty happy with them.

Would you consider europium doped strontium aluminate powder more fitting for the strontium or the europium section?

I know there is infinitely more Sr in there, but Eu is just so hard to get representative samples of!

Have a good day!

~ 0,2g of Lithium under argon.

~10g of sodium under oil. Pretty shiny now, but will probably tarnish with time.

~10g of potassium under oil.

And tiny ampoules of rubidium and cesium (10&15mg).

Pretty happy with these, we'll see how they change with time.
