摘要
在Al2O3-SiO2体系中,分别加入FeO、MgO、Na2O等组分,采用熔融拉丝工艺制备了莫来石连续纤维;通过X射线衍射分析、扫描电镜及能谱等分析,研究了莫来石纤维的形成过程及机理.实验表明:这种工艺能够制备组织形态为针状的莫来石纤维.讨论了采用玻璃纤维坩埚拉丝工艺制备莫来石纤维的可行性,为莫来石连续纤维的工业化推广提供了新的途径.
Mullite continuous fibers were prepared in A1203-SiO2 system by separately adding FeO, Na2O and MgO with a melt/drawing method. The forming mechanism of mullite was investigated by using SEM, XRD and SEM-EDS. The results show that the mullite fibers with a needle structure can be prepared from the method. This is a new approach of preparing mullite continuous fibers in industry which comes from producing glass fibers process with a crucible.
