List of Functions

■ Features thanks to spray decomposition method
1. Composition is uniform and the uniform dispersibility of trace components is excellent.
2. Particles become secondary particles granulated from primary particles.
3. Fine spherical particles with good dispersibility are obtained. (sub-micron to about 10 μm)
4. Particles are porous when formed making them easy to crush during molding.
5. They are easy to sinter due to high surface activity.
6. Composite ceramics can be synthesized as a nanocomposite material by sintering the product powder.
■ Features of the spray pyrolysis devices
1. The core furnace pipe is made of a special ceramic and is indirectly heated by an electric heater.
2. Operation is possible at furnace temperatures of approximately 900ºC.
3. Spraying of solutions and slurries is made possible by a special two-fluid nozzle.
