Bridgman-Stockbarger Crystal Growth Technique
The Bridgman technique is a directional solidification process. The ampoule contains the melt which moves through the axial temperature gradient in a furnace. Single crystals can be grown using either seeded or unseeded ampoules. Many novel organic single crystals have been grown by the unseeded method in our laboratory. The solid-liquid interface has been investigated during growth to improve crystal quality.

Facilities

  • Conventional two-zone BS system for inorganic materials.
  • arious types of transparent BS systems for organic materials with observation systems.

Crystals grown using this technique in our Lab.:

  • Schiff's base materials
  • DIVA and its Derivatives
  • Benzil
  • MHBA
  • Binary Organic crystals (MNA:Benzil)
