Interactions between Molecularly Smooth Gold and Mica ...

2019-12-12  Using a surface force balance, we measured the forces between an ultrasmooth (0.2 nm rms roughness) template-stripped gold surface and a molecularly smooth mica surface. Comparison of these forces in both low salt (conductivity water, equivalent to 10−6−10−5 M 1:1 salt) and high salt (10 mM KClO4) regimes enabled us to examine the properties of water layers confined between a metal

What is gold mica powder? - FindAnyAnswer

Gold will simply bead up. Note that if you don't bend it far enough, mica might spring back since it does have SOME flexibility. If you poke pyrite or mica flakes with a pin, they will usually break apart into even smaller flakes, whereas gold will dent and spread like soft lead. Rub the flakes between your fingers.
