Aqueous solutions (various molarities) of metal nitrate salts along with pre determined quantities of additives is fed via a peristaltic pump and atomized at a particular pressure of compressed clean/dry air is allowed to enter in to a hot zone to under go pyrolysis. The temperature is again a predetermined one for a given composition with the help of thermal analysis.Required temperature in pyrolysing chamber is generated by blowing hot air to have the advantage of cyclonic classification possible for the product powders as a function of their size. Operating parameters for each composition can be stabilized by studying the effect of (solution) feed rate & molarity, pyrolysis temperature and atomizing pressure to achieve the highest yield. Nano powders such as doped/pure ZnO, ZrO2, YSZ, Lanthanum Strontium Manganate-LSM in bulk (kg level) can be synthesized.
Water evaporation capability is 20 litres/ hr.
