Abstract
A method for preparing aerogel particles and a coated component are provided. The coated component includes a substrate and a coating. The coating includes aerogel particles sprayed from a hot gas jet or plasma jet. The method includes the step of feeding one or a plurality of gel particles into a hot gas jet or plasma j et. The one or a plurality of gel particles are sufficiently small to permit supercritical drying during the time the particles are in the jet. The method further includes the step of exposing the one or a plurality of gel particles to the temperatures and pressures of the hot gas jet or plasma jet to create the aerogel particles outside of a jet emitter and/or without a sealed pressure vessel.
