Synthesis of Mullite Whiskers

Journal of the American Ceramic Society, 2002
Mullite whiskers were synthesized by heating a mixture of SiO 2 and silicon in an alumina tube reactor under a flow of H 2 and CF 4 .

Synthesis of Mullite Whiskers and Their Application in Composites

Journal of the American Ceramic Society, 1991
Mullite whiskers were synthesized by a vapor‐solid reaction. Mullite composition xerogels were fired at 900° to 1600°C with AlF 3 in an airtight container. An average whisker increased in length from 7 μm at 1100°C to 10 μm at 1600°C, whereas an average whisker decreased in aspect ratio from ...

Mullite whiskers derived from kaolin

Ceramics International, 2009
Abstract Short mullite whiskers prepared by firing compacts of kaolin and NH 4 Al(SO 4 ) 2 ·12H 2 O powders, with a small addition (0.8, 1.5 wt%) of NaH 2 PO 4 ·2H 2 O, in air 1300 and 1400 °C for 15 h have been characterized in terms of whisker morphology, composition and structure. Relatively uniform whisker shaped crystals grew within the silicate
