Sol-gel method was used to prepare different kinds of sol. After aging, different ceramic fibers with different mg / Si ratios were prepared. The effects of acid silicon ratio, water silicon ratio, magnesium silicon ratio and sintering temperature on the fiber formation and structure evolution of sol were studied. The results show that increasing the content of silica tends to form a continuous network in the structure, which is conducive to improving the stability of fiber formation and the crystallization temperature of the fiber; increasing the ratio of magnesium to silicon leads to the poor fibrillation of the sol; at the same time, the change of composition does not change the crystallization type of the fiber.
