Mullite Continuous Ceramic Fiber Prepared by Sol-Gel Method

摘要

As oxide materials, continuous mullite fiber has superior properties in high temperature resistance when exposed in air. Present work shows the production of oxide solution and the spinning of the mullite fiber. The stable spinning lasted over 10 hours. The strength of the mullite- based fiber is 1900 MPa with a diameter of 10 μm after about 1000℃ treatment. When the treatment temperature exceeds 1300℃, the grains of fiber become column crystals and result in reduction of fiber strength.
