Which Is Correct: Equilibrant or Equilibriant?

[Peppino]

What is the correct spelling of the word? I've always used equilibriant but I've now heard it should be equilibrant. Any insight into this dilemma?

For what it's worth, Google redirects searches for "equilibriant" to "equilibrant", but does not redirect searches for "equilibrant".

"Equilibrant" is the way I learned it.
