Unusual synthetic sapphire shapes are one of PST's areas of expertise. PST grows synthetic sapphire into a variety of shapes such as: domes, tubes, ribbons and shells. The Stepanov synthetic sapphire near net growth method allows shapes to be formed with minimal or no grinding; a cost and time saving benefit.
PST has the flexibility to grow synthetic sapphire to near net shapes. Shapes can be grown to specific orientations or random orientations (lower cost). Typically sapphire tubes and rods are grown with the C-axis parallel to the part axis. Whereas sheet and ribbon are usually grown in the A-plane orientation or R-plane for semiconductor applications. The surface finish for “as-grown” parts varies from clear to a translucent look, depending on the shape and size of the part being grown.
Synthetic sapphire is a superior material for many applications because it is one of the hardest, most wear-resistant, chemical resistant and thermally stable materials available.
