Crystallographic Relations of Biaxial Crystals

  • Richard E. Stoiber
  • Stearns A. Morse


The size, shape, and elongation of biaxial crystals are determined essentially the same way as for uniaxial crystals. The sign of elongation is defined somewhat more completely. Crystals may be elongated parallel to either X, Y, or Z, or to none of these. Crystals elongated parallel to Y are considered to have an indeterminate (±) sign of elongation.
