Abstract: A method of producing fibers includes exposing an inorganic composition to a plasma plume, where the plasma plume has a temperature of at least 1500 °C and a bulk velocity of at least 350 m/s. A system for producing fibers includes a plasma torch to produce the plasma plume and a feeding device to introduce the inorganic composition to the plasma plume.
