AI Technical Summary
The brittleness and sensitivity to defects of existing ceramic fiber materials limit their development in lightweight and elastic ceramic systems. Furthermore, existing preparation methods are difficult to form large-scale three-dimensional networks and suffer from problems such as low preparation efficiency, complex processes, and high costs.
Zirconia ceramic fiber materials were prepared by air-jet spinning based on zirconia nanocrystals. By preparing a spinnable mixture and setting appropriate spinning solution injection rate and air pressure, a three-dimensional zirconia ceramic fiber material with an ordered layered structure was formed. The high compressibility zirconia ceramic fiber material was obtained by high-temperature calcination.
Mass production of highly compressible and high-temperature resistant zirconia ceramic fiber materials has been achieved. These materials exhibit excellent compressive strength and flexibility, solving the problems of brittleness and difficulty in assembling ceramic materials into large-scale three-dimensional networks, and reducing production costs and complexity.
