High density ice
WebThere is much interest in high-density ice (HDA, 1.17 g cm −3 at 0.1 MPa) and very-high-density ice (VHDA, 1.26 g ˣ cm −3 at 0.1 MPa) formed from LDA or crystalline ices. These last three amorphous ices (LDA, HDA, and VHDA) occupy three distinct megabasins in the energy landscape [ 1719 ] but are not required to obey the 'ice rules' and may contain a … WebIt can be prepared by heating high-density amorphous ice from 77 K to about 183 K at 810 MPa.
