Steps in Materials Production

Attention: open in a new window. Print


Typical steps during the manufacturing of materials, i.e. single crystals, are:

  • procurement of the necessary raw materials
  • preparation / purification of the raw materials before crystal growth
  • growth of the single crystals
  • thermal annealing of the grown crystals in vacuum, inert and / or reactive gases
  • cleaning of the crystal surfaces
  • machining of the single crystals
    • i.e. sawing, rounding, facetting, grinding, lapping and polishing
  • epitaxy (= deposition of mono-crystalline layers)
  • conditioning of waste
  • qualification of the crystals


Crystal Growth Consulting optimizes quality control and logistics along the whole value added chain.
