Magnesium aluminate spinel-alumina continuous fiber and preparation method thereof
The invention discloses a magnesium aluminate spinel-aluminum oxide continuous fiber and a preparation method thereof, and belongs to the technical field of electrodeless nonmetal materials. The magnesium aluminate spinel-aluminum oxide continuous fiber crystal phase comprises magnesium aluminate spinel and aluminum oxide crystal grains, and the grain sizes of the magnesium aluminate spinel and the aluminum oxide crystal grains are smaller than 50nm; the magnesium aluminate spinel is dispersed among aluminum oxide grains. The magnesium aluminate spinel-aluminum oxide continuous fiber is small in crystal particle and compact in microstructure; the magnesium aluminate spinel is dispersed among aluminum oxide grains, atoms at grain boundaries of the adjacent grains are arranged in order, the interface bonding strength is high, and good continuity and tensile strength are achieved.
本申请公开了一种镁铝尖晶石‑氧化铝连续纤维及其制备方法，属于无极非金属材料技术领域。该镁铝尖晶石‑氧化铝连续纤维晶相组成包括镁铝尖晶石和氧化铝晶粒，镁铝尖晶石和氧化铝晶粒的粒径均小于50nm；镁铝尖晶石分散在氧化铝晶粒之间。该镁铝尖晶石‑氧化铝连续纤维的晶体颗粒小，微观结构致密；镁铝尖晶石分散在氧化铝晶粒之间，相邻晶粒间的晶界处原子有序排列，界面结合强度高，具有良好的连续性和拉伸强度。
