Sapphire Materials:
Sapphire is grown using various different methods, each with its
advantages. By offering Sapphire grown by Stepanov, Czochralski,
Kryopolus and HDSM methods, Roditi ensure that the specification is
met with the best production time and cost in mind.
Boules, Ingots and Blanks
Unprocessed, single crystal Sapphire takes the form of a boule
before being cut and polished into the required forms.
The boule is a large, cylindrical-like piece of Sapphire with no
ground, polished or flat faces and offers any crystallographic
orientation of components, such as c, m, r and a-cut. Because of
Sapphire's tremendous hardness, the cutting and processing is done
with diamond tools.
Boules such as this are processed into blanks and ingots ready for
further processing and polishing. Such blanks and ingots are
uniformly shaped, usually as cylinders, and have ground surfaces.
