Aluminum particles have been shown to enhance the performance in propellant systems by reacting and releasing significant chemical energy that contributes to the overall heat release. However, the heat transfer characteristics from a propellant to a

Carbon-carbon composites were coated with Calcium Magnesium Zirconium Phosphate (CMZP) and Mg-doped Al2TiO5 sol-gels in order to form an oxygen barrier at temperatures above ∼650°C. The coatings were applied using a dipping technique and controlle

The use of ceramic oxide coatings on silicon nitride is one method to improve its alkali corrosion resistance. Four oxide coatings, including (Ca0.6, Mg0.4) Zr4(PO4)6 (CMZP), zirconia, mullite and alumina, were examined. These coatings were applied o

New (Ca1-x,Mgx)Zr4(PO4)6 ceramics in the ultra low expansion NZP family not only have near zero thermal expansion but also have thermal conductivities lower than those of conventional thermal barrier materials such as ZrO2. In addition, CMZP is less

Porosity in Al and AI-Cu alloys has been examined in cast and directionally solidified material for a range of hydrogen concentrations and freezing rates. The results indicate that no macrosegregation of hydrogen occurs during the freezing process. A
