Processing Aluminum NitrideaSilicon Carbide Composites via Polymer Infiltration and Pyrolysis of Polymethylsilane, a Precursor to Stoichiometric Silicon Carbide

AlN-SiC-particle-reinforced composites have been prepared at lessthan equal to1400 degree C using submicrometer AlN, -325 mesh alpha-SiC particles, and polymethylsilane (PMS; -(CH3SiH)n-) via a polymer infiltration and pyrolysis (PIP) process. PMS is an organometallic SiC polymer precursor that can...

Zusammenfassung:AlN-SiC-particle-reinforced composites have been prepared at lessthan equal to1400 degree C using submicrometer AlN, -325 mesh alpha-SiC particles, and polymethylsilane (PMS; -(CH3SiH)n-) via a polymer infiltration and pyrolysis (PIP) process. PMS is an organometallic SiC polymer precursor that can be modified with 16 wt% cross-linking aid to provide mPMS. mPMS converts to nanocrystalline beta -SiC with >80% ceramic yield (1000 degree C in argon) with some excess (
