| description | Polycrystalline Alumina Articles and Methods of Manufacture Polycrystalline alumina and methods for manufacturing polycrystalline alumina exhibiting improved transmission in the infrared region. In one embodiment, the percent real in-line transmittance is within about 2 % of sapphire at selected wavelengths. In one or more embodiments, polycrystalline articles exhibit improved mechanical properties such as thermal shock resistance and hardness, which may find use in armor applications.
L'invention concerne des articles en alumine polycristalline et des procédés de fabrication d'alumine polycristalline présentant une transmission améliorée dans la région infrarouge. Selon un mode de réalisation, le pourcentage de transmittance en ligne réel est d'environ 2 % par rapport au saphir à des longueurs d'ondes sélectionnées. Selon un ou plusieurs modes de réalisation, les articles polycristallins présentent des propriétés mécaniques améliorées, telles que la résistance aux chocs thermiques et la dureté, ce qui peut être utile pour des applications dans des armures. |
