The effect of novel starting solutions, which contain ammonia as a complexing agent, on the microstructure development of various fine particles by spray pyrolysis was investigated. The particles obtained by this process showed some unique microstructures : e.g. hollow spheres with thin shell, skeletal shells, foam-like, highly segregated composite, etc. Slow drying of starting solution mist at relatively low temperatures was necessary for the development of the structure. It was concluded that evaporation of ammonia from the solution droplets, which occurred faster than the drying, caused the precipitation of the precursor at the surface of the droplet and developed the microstructures. Relatively lower temperature for production was also an advantage of the process proposed here.
