Abstract
A ceramic fiber composite comprises ceramic fibers bonded together by an at least partially ceramic binder formed from a nanoclay and at least one of a ceramic precursor material or a ceramic material. The present invention also concerns methods of forming ceramic fiber composites and burners containing them.
Claims20
A method of making a ceramic fiber composite comprising:
- forming a green substrate from components comprising ceramic fibers;
- impregnating the green substrate with a first impregnation dispersion to provide an impregnated substrate, wherein the first impregnation dispersion comprises water, a nanoclay, and at least one of a ceramic precursor material or a ceramic material;
- drying the impregnated substrate to provide a dried substrate;
- calcining the dried substrate to form a calcined substrate;
- and
- firing the calcined substrate to form a ceramic fiber composite comprising ceramic fibers bonded together by an at least partially ceramic binder, wherein the ceramic fiber composite has a porosity of less than 65 percent.
