I found some interesting materials at a
local fleamarket (http://www.electronicsfleamarket.com):
a canister of lithium sheet metal, and a bottle of fine zirconium powder (325
mesh). The zirconium is stored under water since the dry power can self-ignite,
or may be ignited by static electricity or shock. Confusingly, the MSDS sheets
say that dry
zirconium powder must not be allowed near water, but if it is to
be stored, it must be completely submerged in water. I carefully dried a very
small amount, and sprinkled it over a flame.
If you know of something interesting to
do with these chemicals, please let me know.
hey everyone I
recently picked up a
couple of interesting items at the flea
market one of which is this tin of
lithium under lithium alloy under argon
so let's crack this thing open and see
what's in there so surprisingly the
lithium is actually just here it's a
very thin metal foil I was actually
expecting another container inside here
that would allow me to reseal it
oops so anyway let's cut off a piece of
this and put it in water it's a very
soft metal and as we can see classic
vigorous reaction there you can see the
hydrogen bursting let's try a bigger
piece so the bucket said that this is
90% lithium I'm not really sure what the
other 10% is but it seems like the out
of the metal completely reacts with the
water I only see a trace of of any other
metal in there okay next up is zirconium
powder so this is pretty unusual I mean
zirconium metal is unusual enough but
this is a very fine powder 325 mesh and
it's stored under water so this is the
zirconium powder down here and this is
just water above it and I started
reading up on this and the really fine
zirconium powder is explosive and
pyrophoric meaning that if you expose it
to air it can self ignite which is
always fun so it's stored under water
but a lot of the MSDS
safety sheets say that you can't allow
dry zirconium power to become wet which
is a little confusing why is it stored
underwater if you can't allow the powder
to become wet the trick is that the
powder must be either completely dry or
more than 30% by weight of zirconium in
water
so basically 30% of the mass of the
metal must be water in the container
that it's being held so I don't really
know what the rationale is I tried
figuring this out online but I couldn't
find a clear explanation of what the
deal is there I wanted to draw a small
sample of this but I was already getting
kind of nervous since you're not allowed
to have it partially wet it's okay to
have it completely submerged and it's
okay to have a completely dry but how do
you actually get from completely
submerged to dry without having it in
that sort of danger zone of just a few
percent water so I you know I think they
might be overstating the severity of
this just a bit I started with a tiny
tiny sample and what I did is I just put
it on some filter paper and left this
out outdoors so that it would air dry
and I came back and kind of very
carefully fiddled with the powder with
this spatula and it didn't auto-ignite
and so then I put it over a blowtorch
flame and that ignited it all right but
I mean it was not quite as sensitive as
I thought I was half-expecting the thing
to just catch fire all by itself as it
dried but it didn't happen that way so
instead what we're left with here is the
dry powder it's actually still somewhat
wet so or maybe we're in that danger
zone now who knows I only have you know
maybe a gram or less of it here and what
I'll do is just put some of this over
flames as you can see it burn it burns
with a really white intense flame
I'm really surprised at how little you
need I mean I took a tiny amount out of
powder out of that container and
the teeny little spoonful is all it
takes to make a really big shower of
sparks
I realized that this plastic container
is fairly permeable to oxygen and so I'm
going to have to find a metal container
or glass container to keep that lithium
from from oxidizing so let me know if
you have any suggestions of what I
should do with this I've got 3/4 of a
kilo of lithium and half a kilo of
zirconium powder so besides just
randomly setting them on fire
there might be something work instructed
to do with them obviously the thing to
do with lithium is to make a battery I
suppose but I don't know if you guys
have some other suggestions all right
