I'm trying to figure out what the most polarizable solid that can be used at standard conditions is.

  1. Wikipedia says alkanes are the most polarizable materials: https://en.wikipedia.org/wiki/Polarizability

  2. I also found this table of the polarizability of elements: http://ctcp.massey.ac.nz/2018Tablepol.pdf

From 1) I'd hypothesize parafin wax?

From 2) I'd hypothesize an aqueous gel (OK, technically not a solid, but still useful) spiked with an iodine salt?

    $\begingroup$ Are you looking for materials with the highest epsilon_r? That's probably materials that are being used to make ceramic capacitors like barium titanate. $\endgroup$ Oct 27, 2022 at 18:38
  • $\begingroup$ @FlatterMann I think the symbol for polarizability is alpha. $\endgroup$

  • $\begingroup$ See Clausius-Mossoti for the translation between the two quantities: en.wikipedia.org/wiki/Clausius%E2%80%93Mossotti_relation $\endgroup$ Oct 27, 2022 at 22:09
