Abstract: |
|||
| A process for preparing high-performance continuous fibre of zirconium oxide includes such steps as synthesizing acetylacetone-zirconium polymer as precursor from acetylacetone and zirconium oxychloride as main materials, dissolving in methanol to obtain the spinning solution, drying spinning to obtain continuous fibre of precursor, heat treating in a multifunctional sintering furnace by special atmosphere and high-temp. airflow spraying for stretching. Its advantages are high tensile strength (over 2.6 GPa) and long length up to several kilometers. | |||
