@all

Can we convert Bis-Beta-carboxyethyl germanium sesquioxide back to free germanium?

I belive it would be possible but I think that it would be easier to just grind half a kilo of standard diodes....Ã,

WOWW....

I've prepared some more Rochelle salt and this stuff is REALLY powerful!!!

Still liquid (wet), I applied a jolt of current of 600V and the tin I'm using as container to crystallize the salt, almost jump off the table....even with water the piezoelectric prperties are remarkable.....

Submitted to continous current (around 60V), no bubbles of any kind are developing...I can't imagine the crystallisation results...

Cool....

G'day all,

@sutra: Sounds like an interesting experiment. I don't think it was piezoelectric effect though, it usually requires a ridgid crystal structure. Please let us know how your crystals turn out. Either way, looking at your picture, you've still got more hair than me.

Hi Ian,

well the can jumps if shocked with high voltage ( at least 4 mm), without any spray or ripple...I know that it takes a crystalline scructure to generate a piezo...anyhow the effect it is rather puzzling...I'm checking the positive elecrode and I'm sure I'll end up with metal contamination in the salt...the crystals are growing on the whole inner surface of the can instead of starting from the bottom...it could mean nothing special, since the salt could just find suitable nucleating surface on the side of the can.

cheers

P.S. yeah, in the picture you can't see my long pony tail....
