) analysis for ART (a) form (I) network volume against pressure (GPa) in red. (b) Void volume of form (I) against pressure. (c) Form (II) in silicone oil (blue) and form (III) in petroleum ether (black) network volume against pressure. (d) Form in silicone oil (blue) and form (III) in petroleum ether (black) void volume against pressure. The form (II) to form (III) phase transition is observed between 1.5 and 2.02 GPa in silicone oil. Lines serve as a guide to the eye.
