Method for preparing silicon dioxide/aluminum oxide multiphase ceramic fiber by thread throwing method
The invention discloses a method for preparing silicon dioxide/aluminum oxide multiphase ceramic fibers by a thread throwing method, and relates to a preparation method of ceramic fibers. The invention aims to solve the problems of high temperature requirement, complex process and harsh equipment requirement in a ceramic fiber preparation method. The method comprises the following steps: adding polyvinyl alcohol into deionized water, dissolving the polyvinyl alcohol to obtain a SiO2/Al2O3 precursor solution, preparing a silicon dioxide/aluminum oxide multiphase ceramic precursor solution, injecting the silicon dioxide/aluminum oxide multiphase ceramic precursor solution into thread throwing equipment, throwing threads, collecting fibers by using a collecting device to obtain single continuous fibers, and performing drying; after drying, taking out the fibers and carrying out high-temperature calcination on the fibers. The Young modulus of the obtained fiber ranges from 100 Gpa to 200 Gpa, the tensile strength ranges from 5 Gpa to 13 Gpa, the diameter ranges from 1 micrometer to 10 micrometers, and the using temperature ranges from 1,400 DEG C to 1,600 DEG C. The method is suitable for preparing the multiphase ceramic fiber.
