A high temperature low friction dynamic seal includes a wire mesh base portion and a compressed shell portion on the base portion. The shell portion includes between approximately 2% and 30% of high aspect ratio vermiculite having a mean particle size of less than approximately 50 microns, between approximately 10% and 88% of high temperature resistant fibers and between approximately 10% and 88% of one or more a solid lubricants selected from a group consisting of barium fluoride, calcium fluoride, cerium fluoride and a eutectic of barium fluoride and calcium fluoride. The method of forming the seal includes the steps of forming a compressed wire mesh base portion, applying an aqueous paste-like mixture of the shell portion components to the base portion, evaporating the water from the shell portion and compressing the shell portion and the base portion.
