| Abstract: | Oxygen in different states in ultrafine powders can be determined with newly developed heat-extraction method. XPS, AES and FT IR surface analysing techniques are applied to identify oxygen species and their distribution in powder particles. The ultrafine powders of Si3N4,AlN,TiCN and SiC have been investigated to evaluate the relationships between oxygen content in various states and the samples synthetic process ,particle size and duration in air. |
