Stepanov's method

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
