How to make zinc powder?
« on: 03/08/2011 05:30:58 »
I know of several ways to turn a chunk of zinc into powder: Electrolysis of a molten zinc salt; a more reactive metal in a solution of a zinc salt, taking a file to it. I was wondering if it would be possible to react zinc hydroxide with hydrogen peroxide Zn(OH)2 + H2O2 = Zn + 2H2O + O2. I know this can be done with more noble metals, but I'm not sure if it can be done with as reactive of a metal as zinc. Ideas? Any other methods?

It wouldn't work with Zn.

I was hoping for a little less intensive method. I've tried, but just don't have the patience to sit down with a file and a chunk of zinc.

You probably will have to do electrolysis of a zinc solution, with a cathode made from carbon, and a large zinc anode. The zinc deposited on the cathode can be scraped off regularly in a thin film, which can easily be ground to a power.

What about using a cheese grater or a finer faster method, a machine like a Vitamix...it turns many things hard in nature into a powder.....I use it to grind corriander herb and other hard whole herbs.

Where can I buy a chunk of zink... I would love to test it for you in my Vitamix machine... :-)

Zinc is a fairly soft metal, it is similar to lead in it's properties. but is slightly harder when cast. It will definitely blind any grinder and render it useless in short order.

I have to different chunks of zinc. One is a piece from an old roof (used to keep down moss), and the others I got a while ago from someone in my old school, I'm suspicious that they are from pennies but since he didn't sell it and I'm not going to sell it it's not going back into circulation.
