I dry it with acetone right on the vacuum filter after its been washed. This removes the water and the acetone can be then removed by gentle warming. But depending on your particle sizes you may need the inert atmosphere for it (Nitrogen, Argon) as the fine one can be pyrophoric in air.

∙ 11y agoAssuming you have solid copper you could just grind it into powder. If you don't have access to copper, you could go through a series of chemical reactions that could allow you to obtain copper, though it likely would be easier to just buy some.
Copper oxide, which is a compound from the two elements copper and oxygen. When copper is exposed to oxygen for a long period of time, it begins turning green. The green is Copper oxide.Copper oxide can refer toCopper(I) oxide (cuprous oxide, Cu2O), a red powder;Copper(II) oxide (cupric oxide, CuO), a black powder. (Source wikipedia)
Contacting the iron powder with an aqueous solution of copper (II) salts will produce a copper coating on iron powder: Iron is higher in the electromotive series than copper and therefore will displace copper from the solution, resulting in copper-coated iron and dissolved iron cations. When all of the surface of the iron powder has been coated with copper, the iron will stop reacting because it no longer has access to the copper ions in solution, the access of the iron being blocked by the layer of copper coating the remaining iron powder.

filteration
The copper becomes black!
copper will not 'spark' causing ignition of the powder. Steel can produce a 'spark' causing the powder to ignite................
Copper Carbonate
Iron is magnetic but copper isn't. So I guess iron powder is magnetic while copper powder isn't.:)
Cu2O (Copper(II) Oxide) is a Red Powder. CuO (Copper(I) Oxide) is a Black Powder.
the copper reacts with 02 in the air to make copper oxide, which is black 2Cu+O2--> 2Cuo

Copper Sulfide
You get a grey powder because magnesium is higher up in the reactivity series than Copper - (magnesium is more reactive than copper) therefore when you heat it up there is a displacement reaction. That grey powder is actully magnesium oxide and copper e.g Copper oxide + magnesium = magnesium oxide and copper.
Copper powder reacts with molten sulphur to make copper(I) sulphide (a compound). 2Cu + S -> Cu2S Please see the link.
Okay, let's take the basics: There is no such thing as "copper sulfate baking powder", as it would be poisonous. I can think of no way to relate elemental nickel to the fictitious "copper sulfate baking powder".
