Zinx oxide - Copper oxide
« on: April 23, 2012, 03:14:18 PM »
Hi to all.

What i have:
- zinc oxide powder
- copper oxide powder
- zinc plate
- copper plate
-------------------------------------

1.) How to apply zinc oxide to zinc plate
and
2.) how to make the same but with copper ( copper oxide to copper plate )

Is there any tutorial on this ?
Thank you in advance !

90 view's... So it must be interesting :-)

I dont believe that no one knows how to make this.
Is it so complicated ?

Heat up the plates and oxide will form on the surface.

Made the test plates by heating them but this process takes to much energy/power and it costs much more then some chemical reaction. On the other side, oxide drops down after some time.

I was thinking that i could use ammonium chloride for this.
I can put the plate into A.C. then i can add desired oxide.

Dont know but this should work ...

You can carry out electrolysis with zinc or copper plate as the anode. And use a solution as the electrolyte that would get you oxygen gas at the anode. Then this oxygen gas would react with the metal over time to produce the oxude coated onto the metal itself. But im not sure how long this will take or whether that reaction between the metal and oxygen is feasible enough or fast enough. Probably not going to be very efficient.

How is it different from keeping the metal in contact with the atmospheric oxygen?

Hmm...thats a good point there. I was thinking about the anodising of aluminium that gave me that idea.

Quite different, especially due to the high energy associated with the freshly prepared oxygen atoms. Some oxygen atoms react with the Metal electrode to form the oxide, some combine with  another Oxygen atom to produce Oxygen molecules. These might react with the metal to form the oxide or go off as a gas

Bleach (NaClO) will oxidize many metals on contact (I have witnessed the reaction on Fe).

So try and dip your Zn (or Cu) in some inexpensive bleach.

I would expect:

 Cu + NaClO --> NaCl + CuO

and this should easily add an metal oxidize layer.
