Abstract: A method for producing a plate type metal-silica composite aerogel and a plate type metal-silica composite aerogel produced thereby in which the metal salt concentration and the basic catalyst concentration are adjusted to form a plate type intermediate first, and then an appropriate amount of a water glass solution is added, thereby enabling the plate type metal-silica composite aerogel to be produced in a short time under conditions of low temperature and atmospheric pressure, so that the process is simpler than the conventional production method, and the cost is reduced, which is excellent in economy. Also provided is a plate type metal-silica composite aerogel, which is produced by the claimed method and has excellent dispersibility that requires no additional surface modifier.
