High Strength, Optical Quality Spinel Navy SBIR FY2010.2 Sol No.: Navy SBIR FY2010.2 Topic No.: N102-163 Topic Title: High Strength, Optical Quality Spinel Proposal No.: N102-163-1392 Firm: CeraNova Corporation P. O. Box 278 Hopkinton, Massachusetts 01748-0278 Contact: Mark Parish Phone: (508) 460-0300 Web Site: www.ceranova.com Abstract: Optical quality polycrystalline spinel (MgAl2O4) has been sought as a visible- and infrared-transmitting material since the 1960s because of its potential for transparent armor and durable sensor window. Recently, there have been great strides in the processing of transparent spinel that has shown great promise in optical clarity, however, the improvements in strength of spinel has not been as successful. CeraNova proposes a method to produce a very fine grained transparent spinel in an economic manner that has proven advantageous to increase strengths by multiples in similar materials while maintaining optical clarity. Benefits: Through CeraNova's technical strengths in processing of nanopowders, achieving high green density with uniform microstructures, and oxide sintering expertise, we expect to achieve superior spinel properties than have not been demonstrated elsewhere. This achievement will make possible a new and exciting cost-effective window and armor material for DOD applications and commercial applications. Return
