Aluminum silicate fiber reinforced oxide ceramic and preparation method thereof
The invention relates to aluminum silicate fiber reinforced oxide ceramic. The aluminum silicate fiber reinforced oxide ceramic adopts one or a mixture of more of mullite, aluminum silicate, aluminum oxide and silicon oxide as a ceramic substrate and adopts aluminum silicate fiber as a reinforcing phase. The preparation method comprises the steps: carrying out heat treatment for an aluminum silicate fiber fabric, and removing adhesive on the surface of the fiber; taking oxide sol as a precursor, vacuum impregnating the pretreated aluminum silicate fiber fabric, then carrying out the gelatination, carrying out high-temperature ceramization, and completing primary compacting process; repeating the steps for at least ten times, so as to prepare the aluminum silicate fiber reinforced oxide ceramic. The product is excellent in mechanical property and antioxidant property and has the advantages of short preparation period, low cost, capability of realizing near-net shape and the like.
