Development of a Process for Producing Transparent Spinel Bodies.

摘要

Hard,strong,high modulus transparent materials are needed for windows acting as protection against armor piercing projectiles. Available materials include systems containing glasses (noncrystalline) and ceramics (crystalline). The development of a process that can produce ceramic materials without limitations of thickness,costs and shape is the goal of the present study. The ceramic chosen for investigation was magnesium-aluminum spinel (Mg Al204),because of its ballistic properties and a crystal structure which assured acceptable optical properties. (Author)
