|Shaped Crystals is a principle new class of materials. With a Shaped Crystal Growth technology it is possible to add shape to a matter at the growing stage. For Sapphire hardness is very important to be growned by SCG to minimize mechanical treatment.|
SCG technology is leading in producing sapphire rods, tubes, ribbons and sapphire crystals with more complex shape and cross-section.
SCG technology was invented by russian scientist A.V. Stepanov in Ioffe Physico-Technical Inst., Saint-Petersburg in 1938. This technology called lately "Stepanov technique".
Basic idea of Stepanov technique:
The melt moves to a cold zone due to a surface tense forces. The Shaper adds a desired shape to a crystal in a liquid phase.
Modern variations of this method measuring in tens today.
- High temperature insulators
- Precise mechanics
- Human bones prosthesis
- High pressure lamps
