• These channels permit a variety of ions, neutral atoms, and molecules to be incorporated into the crystal thus disrupting the overall charge of the crystal permitting further substitutions in aluminium, silicon, and beryllium sites in the crystal structure. (wikipedia.org)
  • This is because salts do not fit within the hollows of the lattice structure (a regular repeated three-dimensional arrangement of atoms, ions or molecules) of ice - and, thus, the salts dissolved in water are expelled while water freezes to ice. (waterjournal.org)
