Paper Title:
Study on Manufacture of Short Mullite Fibers by Andalusite Mineral of Mei County China
  Abstract

The short mullite fibers were manufactured by andalusite mineral raw materials of Mei County China through isothermal sintering process between 1350°C and 1550°C under the oxidation atmosphere. And then the process which andalusite mineral raw materials of Mei County China had transformed into short mullite fibers was analyzed by X-ray automatic powder diffractometer D/MAX-2400, and the property of morphology of short mullite fibers was observed by scanning electronic microscope QUNATA200. The result manifests that in the range of experimental temperature, andalusite mineral raw materials of Mei County China fully transforms into mullite phase after the specimen is kept warm for 3 hours under sintered temperature 1450°C, and the mullite phases which are transformed at sintered temperature 1450°C mostly present in the form of short fiber while the temperature naturally cools to room temperature with furnace, and this kind of short mullite fiber has the best crystallinity, and the least structural defect and the highest length to diameter ratio.
