Can Current be Applied to Potassium Hydroxide to Create Heat?

It is conductive, specially in aqueous form (as used in making batteries).

To create heat though?

You'd be better off using caustic potash for producing biodiesel.

that's not a no...

You are correct, I did not say no, nor did I say yes. Hmmm, now I wonder why you would want to create heat by electrifying KOH?? Is it partially aqueous? Are you in a RH 29% or more environment? Consider this, what combinations of elements might not warm, when introduced into an electrical circuit? How large of an amount are you wanting to heat?

What does relative humidity have to do with it? Maybe KOH is not the answer. I am looking for a substance that I can dispense with a table top dispenser that when dried or cooled, can be used as a low heat heating element.

For starters, KOH is caustic so you definitely do not want it on your table ! I wondered what your RH was because I wondered if you were trying to dry it out. Hence all my questions about what you were trying to do. It helps all of us help all those who ask questions, if we can get some more information. I would look into the chemicals used in hand and toe warmers; iron, activated carbon, cellulose, salt, and vermiculite, and water in a side reservoir.

I am looking for a material that I can dispense as a gel/liquid, at relatively low heat, that when cured, a current can be applied to create heat. My goal is to create custom heating elements. A metal is an obvious choice, but I don't want to deal with the heat it takes to melt it.

Only one comes to mind, a dense carbon aerogel chemically treated to be hydrophobic. The density will allow conductivity, but that's going to be expensive. I'll think about it, sounds like an interesting invention.

The help is greatly appreciated!!!
