Abstract: The present invention relates to a flame reaction material, particularly a gas combustion flame reaction material for gas combustion appliances and a flame reaction member thereof. The gas combustion flame reaction material is formed by a single alkali metal or alkaline earth metal compound, and said alkali metal or alkaline earth metal compound has a melting point lower than combustion temperature of combustible gases and produces a crystal after high-temperature combustion. The flame reaction member comprises a substrate and a flame reaction material adhered to the surface of the substrate in the form of crystal. The substrate is a metal conductor. Because the gas combustion flame reaction material is formed by a single alkali metal or alkaline earth metal compound, the proportion of it to other materials is not required to consider when fabricated and thus it is convenient to produce.
