Here is a question for the chemistry literate people out here.
As I was screwing down my Ni200 coils, I thought; why not turn temp control off and make these bad boys glow to get rid of whatever manufacturing oils that may be left on the wire, kanthal style.
Upon doing that I noticed my coils changing color, hence oxidizing. To me they look bluish but my colorblindness makes this observation unreliable at best.
Anyhow, I went on good'ol Wikipedia and search for Nickel Oxide. There seems to be two kind of Ni oxide, one green, one black and from what I gathered the black one is not well understood. But here is what it says about the green one or more formally Nickel(II) oxide:
So, after reading this I was wondering at what temperature NiO was produced:
I know my coils are not powder but I witnessed this color change, my pinky tells me that it is oxidizing. 400 °C is around 750 °F which in turn is well above the temp control upper limit of the DNA40 board. I therefore decided not to glow my coils anymore and I am considering wiping my Ni200 wires with aceton to remove any oily residue that might be present on the said wire, as recommended by Evolv.
Long story short:
Do you think that NiO is suceptible to leach into the vapor? Or is it securely fixed to the wire and not leach?
