WebThe ice crystal. The ice. crystal. At standard atmospheric pressure and at temperatures near 0 °C, the ice crystal commonly takes the form of sheets or planes of oxygen atoms joined in a series of open hexagonal rings. The axis parallel to the hexagonal rings is termed the c -axis and coincides with the optical axis of the crystal structure. WebOther acid paths to crystal cores include the dissolution of surface-reaching inclusions and the percolation of acid across zones with high defect densities. In highly crystalline samples dissolution is crystallographically controlled with dissolution proceeding almost exclusively along the c axis.
