Abstract
An automated controlled heat extraction system (CHES)® has been developed to produce 300 kg, 500 mm diameter sapphire boules. The versatile process allows production of boules in a-, r- or c- orientations. The technological advancements come with major cost reductions making sapphire for consumer electronics, LEDs and large optical windows a reality. In addition, these features allow large scale production with a fast ramp rate.
