Paper Abstract

The properties of sapphire make it an ideal choice for future high speed missile applications compared to other existing or emerging materials. High fabrication cost and low material utilization from a sapphire boule cause high costs for sapphire domes. Significant improvements have been made by growing sapphire boules with (0001) orientation and contour slicing. A more desirable approach is to produce near net-shaped sapphire blanks directly from the melt. The feasibility of producing crack-free near net-shaped blanks with controlled inside and outside curvature from the melt in (0001) orientation has been demonstrated using the Heat Exchanger Method (HEM).
