  Crystallization  \Crys`tal*li*za"tion\ 
  (kr[i^]s`tal*l[i^]*z[=a]"sh[u^]n),  n.  [Cf.  F. 
  cristallization.] 
  1.  (Chem.  &  Min.)  The  act  or  process  by  which  a  substance  in 
  solidifying  assumes  the  form  and  structure  of  a  crystal, 
  or  becomes  crystallized. 
 
  2.  The  body  formed  by  crystallizing;  as  silver  on 
  precipitation  forms  arborescent  crystallizations. 
 
  Note:  The  systems  of  crystallization  are  the  several  classes 
  to  which  the  forms  are  mathematically  referable.  They 
  are  most  simply  described  according  to  the  relative 
  lengths  and  inclinations  of  certain  assumed  lines 
  called  axes;  but  the  real  distinction  is  the  degree  of 
  symmetry  characterizing  them  1.  {The  Isometric,  or 
  Monometric,  system}  has  the  axes  all  equal,  as  in  the 
  cube,  octahedron,  etc  2.  {The  Tetragonal,  or  Dimetric, 
  system}  has  a  varying  vertical  axis,  while  the  lateral 
  are  equal,  as  in  the  right  square  prism.  3.  {The 
  Orthorhombic,  or  Trimetric,  system}  has  the  three  axes 
  unequal,  as  in  the  rectangular  and  rhombic  prism.  In 
  this  system,  the  lateral  axes  are  called  respectively, 
  macrodiagonal  and  brachydiagonal.  --  The  preceding  are 
  erect  forms,  the  axes  intersecting  at  right  angles.  The 
  following  are  oblique.  4.  {The  Monoclinic  system}, 
  having  one  of  the  intersections  oblique,  as  in  the 
  oblique  rhombic  prism.  In  this  system,  the  lateral  axes 
  are  called  respectively,  clinodiagonal  and 
  orthodiagonal.  5.  {The  Triclinic  system},  having  all 
  the  three  intersections  oblique,  as  in  the  oblique 
  rhomboidal  prism.  There  is  also:  6.  {The  Hexagonal 
  system}  (one  division  of  which  is  called  Rhombohedral), 
  in  which  there  are  three  equal  lateral  axes,  and  a 
  vertical  axis  of  variable  length,  as  in  the  hexagonal 
  prism  and  the  rhombohedron. 
 
  Note:  The  Diclinic  system,  sometimes  recognized,  with  two 
  oblique  intersections,  is  only  a  variety  of  the 
  Triclinic.
