Go to www.ebay.com, and search for ';zinc powder';. At the moment, there are a number of sources listed, many at reasonable prices. See below for a direct link (Be sure what you buy is the metal powder, not one of the compounds. Zinc metal powder or zinc dust).

Added note: Contrary to what's been said (at least in the USA) obtaining such materials as zinc powder and most other chemicals is not at all difficult if you are a commercial or educational buyer. Lab supply houses will happily sell to commercial, industrial, or educational customers. For certain items, shipping may be difficult or expensive, however

Many suppliers are unwilling to sell chemicals to private persons (for a number of good reasons), but in general the purchase of most chemicals by individuals is still legal (at least in the USA). While the major suppliers will not sell to you as an individual, there are some specialty suppliers for many materials. Ebay is a good first place to try. Failing that, try ceramic and pottery suppliers and other sources such as www.skylighter.com or www.firefox.com. Note that these sources in general will sell only to persons of legal age, however.Were can i get Zinc metal powder?
It is extremely hard to get zinc powder these days, due to its high flammability. You can try a laboratory supplier, but even lecturers and researchers have a hard time getting it.
Any scientific catalog. e.g. Fischer or Merck.

Redox reaction between zinc powder and aqueous copper nitrate?

Zn (aq) + Cu(NO3)2 yields Zn(NO3)2 (aq) and Cu (s).

Why is the copper displaced by zinc black in color and not brown in color? The original copper powder is brown in color.Redox reaction between zinc powder and aqueous copper nitrate?
I suspect that there must be an oxide coating on the copper grains. This doesn't happen if you use iron filings and copper sulphate (or nitrate) solution - you get lovely brown copper powder.

Why does zinc granules often appear to have a white powder on their surface?

ZnO

It's been oxidized by the air. Hey - maybe it could be Zn3N2 (zinc nitride) since nitrogen is more prevalent in the air - don't know the color of Zn3N2, might be both.Why does zinc granules often appear to have a white powder on their surface?
Zinc reacts with the air and forms a coating of zinc oxide on its surface
