Abstract
This SBIR Phase I projects will develop magnesium aluminate spinel (MgAl2O4, referred as spinel from here forth) windows with strength of 350 MPa and Weibull modulus higher than 6. To produce the spinel with the strength of 350 MPa, the microstructure of the spinel will be tailored by controlling the processing parameters, such as impurities of spinel powder, agglomerates in spinel powder, amount and types of the sintering aid, and sintering time and temperature. The spinel windows with little residual flux, from the sintering aid or impurities of spinel powder, and no residual strain will be developed.
