MM&T Manufacturing Methods for Gradient Furnace Processing of Ceramic Armor and Structural Ceramics
Abstract
The growth of large single crystal materials opens up many possibilities for new applications of ceramics, such as in the case of transparent armor, lasers, and laser windows. Single crystals of sapphire have been made by many techniques, the best known probably being the Verneuil method for the production of jewels and bearings. Until recently, the largest crystals of sapphire were probably those obtained by the Czochralski technique where crystals up to three inches in diameter were grown. At the Army Materials and Mechanics Research Center (AMMRC) a coordinated in-house effort has been underway to develop an improved approach to the growth of large uniform single crystals of sapphire. The main effort centered about a research and development project on the gradient furnace synthesis of advanced ceramics.
