Abstract: PROBLEM TO BE SOLVED: To effectively use a combustion gas and to decrease the running cost by forcedly sending air heated by a heat exchanger in a high temp. furnace to eject the air through a hot air ejection nozzle into a reaction tank, while ejecting and dispersing a composite material comprising mother particles with deposition of smaller particles in the ejection hot air. SOLUTION: LPG in a gas cylinder 1 is changed into a combustion gas by a vaporizer 2 and combusted by a combustion burner 4. The produced gas is used to heat a heat exchanger 6 in a high temp. furnace 3 and to heat external air passing through the heat exchanger 6 to produce a hot air. The hot air is ejected through a hot air ejection nozzle 14 into a reaction tank 15. A composite material is also supplied to a nozzle header 16 of the reaction tank 15 and is ejected into the flow of the hot air so as to disperse the composite material by collision of the hot air flow and to integrate the mother particles with smaller particles. When the melting point of the mother particles is higher than that of the smaller particles, the surface of the mother particle melts to form a sphere, on which the smaller particles deposit.  If the melting point of mother particles is higher than that of the smaller particles, the smaller particles melt and form a film on the surface of the mother particle.
