| Abstract | Yttrium silicate is promising materials for the environmental barrier coatings. In this paper, yttrium silicate fiber was successfully prepared by electrostatic spinning, and the microstructure of yttrium silicate fibers was modified by the titanium silicide to improve densification degree of the fiber. In this study, the colloids were obtained by using yttrium nitrate and ethyl orthosilicate as the main raw materials, and the processes such as time and high-temperature calcination were researched. Moreover, the yttrium silicate fibers with different morphologies were obtained by using different proportions of different temperatures and adding different amounts of titanium silicide. The characterization methods such as TG-DSC, SEM, and XRD were used to investigate the preparation process of yttrium silicate fibers. The results show that the temperature has a great effect on the composition of compounds and the morphology of yttrium silicate fibers. The yttrium silicate fiber has the best structure with 15% mixing amount of titanium silicide.
