Al-Mg complex-phase oxide continuous ceramic fiber and preparation method thereof
The invention discloses an Al-Mg complex phase oxide continuous ceramic fiber and a preparation method thereof. Comprising the following steps: 1) carrying out melt spinning on an Al-Mg complex-phase oxide ceramic precursor to obtain a fiber precursor; (2) carrying out non-melting treatment on the fiber precursor to obtain non-melting fiber; and 3) sequentially carrying out inorganic treatment and ceramization on the non-melting fiber to obtain the Al-Mg complex-phase oxide continuous ceramic fiber. According to the preparation method of the Al-Mg complex phase oxide continuous ceramic fiber, melt spinning fiber forming is adopted, the process is simple, environment friendliness is achieved, and large-scale production is facilitated. The crystal form composition of the Al-Mg complex phase oxide continuous ceramic fiber provided by the invention is a mixture of alpha-Al2O3, gamma-Al2O3 and MgAl2O4, and the proportion is adjustable. The average diameter of the Al-Mg complex phase oxide continuous ceramic fiber provided by the invention is 5-20 microns, and the tensile strength is not less than 1.0 GPa.
