Does anyone know what this is??? Does anyone know how to puirify it…? its the stuff that surrounds the battery acid…..

Well Manganese dioxide is in big 1.5volt batteries.Its black so I presume were talking about the same thing.As far as I know the only use it has is as a catalyst in chemical reactions,but nothing particularly useful if youre not into chemistry.It doesnt explode or anything.

well some ass hole told me that it would burn so i ook apart about 100 batterys so i have like 50 pounds of the shit!

Well if you use it as a catalyst for something only a tiny amount is used so you will have that 50 pounds for a long time yet!LOL

I burned it all it did was smell funny and make like a little spark and that was about. I got it outta a AA battery. Not too much fun. Try drinking the acid it might prove to be fun lol just kidding

if you read one of fourms it says you can make a bomb out of this stuff  somthing about putting it in a bottle (plastic) ad then filling the bottle up with hydrogen proroxside that stuff that cleans cuts in the bottle
its like a pressure bomb!

its in the explosives section the last time a saw it

That black shit in carbon-zink batteries is an oxygen source to react with hydrogen bubbles that would form around the center electrode ( a carbon rod ). With out the black stuff, the bubbles would coat the carbon rod after a bit of use and the out put of the battery would go down. Oxygen from the black stuff reacts with the hydrogen to form water.  Contrary to what many people have been misinformed, this type of battery does not contain an acid, instead it contains Ammonium Chloride ( chemically speaking it is a salt ) to eat up the zink shell. This chemical is used in some table salt substitutes ( one brand name is CO-Salt ), also used in some soldering fluxes and cough medicine.
 The black shit ( manganese dioxide ) is not soluble in water so it could be rinsed to remove the other chemicals and then, after being dried, mixed with powdered zink or aluminum to make a flair.

On contact with hydrogen peroxide, the hydrogen peroxide will decompose releasing its extra oxygen atom and leaving water. No perminent chemical change happens to the black stuff.  You might notice that when hydrogen peroxide is poured onto a cut, all the bubbling that takes place. These bubbles are oxygen also, they form by contact with the hemogloblin (iron oxide )  in your blood, and kill germs by oxydising them ( a form of slow burning ).

I used to play around with it when I was younger, I’d put it in a small plastic container and just add peroxide to it, it makes a cool looking smoking/bubbling effect and it heats the container.

After a battery is spent, would the manganese dioxide still be?, or would it just be manganese?
