Abstract

Silicon oxynitride precursors with different nitrogen content were synthesized from hydrolysis and ammonolysis of SiCl₄. Pyrolyses of the precursors were completed from in-situ polymerization and inorganic conversion via amino group releasing. Silicon oxynitride ceramics were successfully fabricated by hot-pressing of resulted powders. Analysis results indicated that crystallization temperature of silica was increased 150 C by introduction of nitrogen, mechanical properties of silicon oxynitride were significant increased by proper crystallization, Flexural strength and fracture toughness reached 156MPa and 1.8MPa · m^1/2 for the material with 24.3 mol% nitrogen sintered at 1400 C, being 4.58 and 2.25 times of that of SiO₂ matrix material respectively.
