Title: Extreme synthesis of crystalline aerogel materials from amorphous aerogel precursors

Patent ·
OSTI ID:1600291

A method includes positioning a porous structure in a pressure cell; injecting an inert pressure medium within the pressure cell; and pressurizing the pressure cell to a pressure that thermodynamically favors a crystalline phase of the porous structure over an amorphous phase of the porous structure to transition the amorphous phase of the porous structure into the crystalline phase of the porous structure.
