Product Description
Manufacturing Process
Stepanov's Method enables the growth of monocrystalline sapphire components in various configurations including rods, pipes, and tapes. The Horizontal Directed Crystallization (HDC) technique combines elements of directed crystallization and zonal melting for superior crystal synthesis.
This advanced method involves slow movement of a local melted zone along a boat-shaped container with furnace charge. HDC provides exceptional cross-section consistency and allows for growing sapphire monocrystals of any crystallographic orientation in plate forms with record sizes unattainable through other growth methods.
