Shaped Crystals is a principle new class of materials. With a Shaped Crystal Growth technology it is possible to add shape to a matter without any mechanical treatment. For some materials it is impossible to add shaped except by SCG technology.

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. Our group was foundated by him for farther investigation and development of 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.
