Summary
Amorphous silicon oxynitride fibers (Si-O-N) have been shown to possess extraordinary high-temperature properties. They are chemically and structurally stable up to 1400°C in nitrogen, 1300°C in argon and 1200°C in air. The fibers as processed have a submicron diameter and a length of several centimeters. Production of discontinuous, long-staple fiber mats has been performed by a single-step process running at 1450°C with SiO2, SiC, Ti powder and NH3 gas as raw materials. Up to 50g of submicron fibers can be synthesized in a batch run. Due to their as processed morphology and high-performance properties, the Si-O-N fibers are promising for use in high-temperature applications such as hot-gas filters, high temperature catalysts support, insulation material and as reinforcement filler in CMCs and MMCs.
