99% sure it's the same, but 2 problems:
1) Ceramic wicks need to be baked in a kiln after production - So unless you have something that can reach those temperatures (1800º F iirc) then using this material un-treated poses health risks.
2) I believe I read in a thread that some vendors will check to see what you're using it for, so OMEGA might not even sell to you if you say you're using for vaping to avoid lawsuits (See reason 1).
Though to be honest... I've tried some from RBA Supplies, and I wasn't impressed. It works, don't get me wrong, but it wasn't the "OMG" experience I was expecting for the price. I'm much happier using SS/cotton.
