Morph-genetic Al_2O_3 ceramic derived from bio-templates

This paper puts forward a new thought,that was using cotton fiber as template to produce Al_2O_3 fiber ceramic.By using X-ray diffraction,scanning electron microscope,and ASAP 2010 system,we test and analyze the micro-structure and characteristic of the ceramic oxide we produced.The experimental results show that the Al_2O_3 successfully reserved the cotton fiber structure.Under different sinter temperature,the products we get has different crystal type.The higher the temperature,the more stable the structure it becomes,the transformation is as follows: amorphous Al_2O_3→γ-Al_2O_3(crystal)→ α-Al_2O_3(crystal).Specific surface area and average pore diameter test shows that different producing methods and directions have great infection on the experimental results.
