Abstract:
A fibrous ceramic material comprises a plurality of fibers having a RxMg2Al4+xSi5−xO18 or RxMg2−xAl4Si5O18 compositional structure. The fibrous ceramic material is form by combining two or more RxMg2Al4+xSi5−xO18 or RxMg2−xAl4Si5O18 precursors in which at least one of the two or more RxMg2Al4+xSi5−xO18 or RxMg2−xAl4Si5O18 precursors is in fiber form. The fibrous ceramic material is shaped to form a fibrous body in which at least about 20% of all fibers therein are aligned in a substantially common direction.
