Abstract

A new ceramic, nitrogen-stabilized aluminum oxide spinel (ALON), has been developed at AMMRC which may have distinct advantages over sintered polycrystalline a-A1₂0₃. This material is isotropic and has been fabricated into dense, transparent bodies with the following properties: Knoop (100) hardness of 1800, elastic modulus of 46x10⁶ psi, a room temperature fracture strength of 45x10³ psi, a dielectric constant and loss tan%ent, respectively, at 10 MHz of 8.56 and 0.0004, trivial oxidation in air up to 1200 C and IR cutoff at 5.2 μm, and an average thermal expansion coefficient (a) of 7.00x10-⁶C -1 (25Ã‚Â°C-1000Ã‚Â°C).
