以粒度≤15μm的铝粉和结晶氯化铝按照物质的量比为3．4∶1混合得到无色透明的氯化铝溶胶，接着向氯化铝溶胶中加入含有酒石酸封端剂的硅溶胶获得莫来石纤维前驱体溶胶。研究了酒石酸添加量（w）为1％、2％、3％、4％和聚乙烯醇纺丝助剂添加量（w）为0．25％、0．5％、1％、1．5％、2％以及不同固含量（质量分数，5％～65％）对莫来石纤维前驱体溶胶纺丝性能的影响。结果表明：酒石酸和聚乙烯醇的加入对莫来石纤维前驱体溶胶的纺丝性能有显著影响，当添加3％（w）的酒石酸和1％（w）的聚乙烯醇时，纺丝性能最佳；在固含量为57％（w）时，莫来石纤维前驱体溶胶呈现剪切变稀特性，其纺丝性能最优。

Mullite fiber precursor sol was prepared by mixing aluminum powder (size ≤15 μm)and crystal aluminium chloride with molar ratio of 3.4 1,then adding silica sol containing tartaric acid capping agent. The effects of tartaric acid addition (1%,2%,3%,4%,in mass,the same hereinafter),spin finish aid poly-vinyl alcohol addition (0.25%,0.5%,1%,1.5%,2%)and solid content (5%-65%)on the spinnability of mullite fiber precursor sol were studied.The results show that the best spinnability can be obtained with 3%tartaric acid and 1% polyvinyl alcohol;when the solid content is 57%,mullite fiber precursor sol shows the shear thinning behavior,performing the best sol spinnability.
