Title: Ultra-High Density Nano-Grained Multispectral YAG Windows
Agency: DOD
Contract: N68936-12-C-0100
Award Amount: $79,998.00
 

Abstract:

Texas Biochemicals Inc, proposes to develop Polycrystalline Yttrium Aluminum Garnet (YAG) as a cost effective material to replace Sapphires for IR transparent multispectral (1-5 microns) sensor windows. We have recently developed a novel technology to produce mono-dispersed, non-agglomerated and ultra-high purity YAG nano-powders. These powders with grain growth reducing sintering additives were used to produce flat IR transparent nano-grained samples by a novel route. Preliminary results showed high stiffness (~ 330 GPa Young"s modulus), and low optical scatter due to small grain size. In the Phase-I project, we will demonstrate that the material conforms to the requirements of optical transmission, optical scatter, mechanical strength and Young's modulus. A DoD prime contractor's facilities will be used for sample evaluations, with whom we have established an on-going collaboration for the manufacture of ZnS for IR domes and windows applications. Cost estimation and a path forward to manufacture sizes needed by the US Navy will also be addressed in Phase I. On a follow-on Phase II project, we will demonstrate durability, repeatability, and fine tune the fabrication procedures for needed sizes. Collaboration with a DoD prime contractor who is highly interested in this technology will facilitate rapid insertion of the technology for commercialization.
