Method for obtaining hollow zirconium oxide fibers by using mudar flosses

The invention discloses a method for obtaining hollow zirconium oxide fibers by using mudar flosses. The method comprises the steps of mixing zircon salt and a yttrium stabilizer, which are taken as raw materials, according to a proportion, and then dissolving an obtained mixture into alcohol to prepare a solution, wherein the volume fraction of the alcohol is 50%; dipping the mudar fibers into the solution, soaking for a period of time, and then squeezing to dry; taking out the product, drying, and then sintering in the oxygen atmosphere so as to obtain the hollow zirconium oxide fibers. The zirconium oxide fibers prepared by the method are different from solid fibers prepared by the traditional method; the zirconium oxide fibers have hollow tubular structures; when the fibers are pressed into a fiber board and stacked together, the air is divided into smaller spaces; in a heat transfer process, the flow of the air is more difficult than that in the solid fibers; the heat-insulating property of the material
