The oxidation behavior and oxidation mechanisms of monolithic ZrB2 and particulate-ZrB2 matrix composites were reviewed. Dispersion of SiC particles into ZrB2 was found to be an effective way to prevent extensive oxidation. However, the formation ...

We describe the fabrication of in-plane randomly oriented short carbon fiber-dispersed ZrB2-SiC (Csf/ZS) and ZrB2-SiC-ZrC (Csf/ZSZ) matrix composites with different slurry compositions using Si-melt infiltration (Si-MI). We also carried out micros...

The oxidation behavior of four ZrB2-SiC-ZrC compositions with varying ZrC contents (20, 34, 50, and 64 vol.%) was compared to that of ZrB2-SiC. The ceramics were oxidized at 1700 °C in an oxygen-hydrogen torch environment. The liquid oxide on the ...

We present an overview of the thermal and mechanical design of the Payload Module (PLM) of the next-generation infrared astronomy mission Space Infrared Telescope for Cosmology and Astrophysics (SPICA). The primary design goal of PLM is to cool th...
