Ice Ih

Special Bonus Round: How can High-Pressure Ices Improve Life for Me Personally?

Ice II

Ice V

Compression-Rate-Related Phase Change in Ice

or, How to Create Exotic Ice Polymorphs by Hitting Things with Very Large Rocks

Convection model: more conducive to melt-refreeze creation of Ice III?

Shaded area shows temperatures and pressures typical of icy satellites (Bauer 2008)

Different onset of phase transition

Initial temperature of shocked material must be cool enough that shock heating doesn't bring it above the quench temperature.

Ice II

Absolute Pressure versus Compression Rate

Ice III

Similar densification

- in a natural setting?

Impact-created melt refreezes at high pressure

- in the lab?

How can we achieve high compression rates?

Question: Can ice polymorphs survive on the surface after formation?

Answer: Yes, provided temperatures don't get too high.

1 GPa

1000 GPa
