Sapphire (single crystal aluminum oxide) is the most commonly used material in infrared transparent windows and domes in `heat seeking' missiles. A replacement for sapphire is sought for improved performance in high speed missile applications, and at the same time, reduce the cost of the windows and domes by a factor of two. High purity fine grained (
