Hello there.I have some barium nitrate which has formed something like rocks,if you can understand me, and i want to milled it in order to make it fine powder.So i put it in my ball mill,of course in an new jar with some lead balls.What i noticed is that the colour of barium nitrate changed from pure white to grey and this happens because lead is contaminating it.

And i want to know if that is as dangerous as i think and what else can i do in order to make it be fine powder.Thanks

I believe Lead Dioxide is sometimes used as a catalyst but otherwise I can't see how it'd dramatically increase the sensetivity of any composition. Poison should not be a concern, barium is already quite poisonous.

You may want to try a simple $10 coffee grinder. I use those to grind nitrates before I make any composition with them.

It's bizzare that your barium nitrate has formed rocks though. I've never had that problem before.

I have had the problem of very finely milled Barium Nitrate forming one very solid lump that needed smashing with a hammer. It would pass through a sieve if grated against it, but it was difficult, much easier to chuck it in the mill for a while.

Although I have not had this problem with the coarser grades of Barium Nitrate.

It's pretty common for Ba(NO3)2 that has been sitting in a warehouse for a few years. Mine was the same way mostly. I just grate it against a relatively coarse screen to break it up as I use it. Sr(NO3)2 is the same way. Most fine powders will do this actually. I've had a drum, seriously that was one solid cake of Mg. I had to break it all up with an ice pick.
