Crystal Growth
A crystal is a solid material whose constituent atoms, molecules, or ions are arranged in an orderly repeating pattern extending in all three spatial dimensions. Crystal growth is a major stage of a crystallization process, and consists in the addition of new atoms, ions, or polymer strings into the characteristic arrangement of a crystalline Bravais lattice. The growth typically follows an initial stage of either homogeneous or heterogeneous (surface catalyzed) nucleation, unless a "seed" crystal, purposely added to start the growth, was already present.

Famous quotes containing the words growth and/or crystal:
“When I have plucked the rose,
I cannot give it vital growth again,
It needs must wither. I’ll smell it on the tree.”
—William Shakespeare (1564–1616)
“Comets, importing change of times and states,
Brandish your crystal tresses in the sky.”
