| ZnO nano powders, which have different morphologies and agglomerate structures, were continuously produced
from Zn(NO3)2.6H2O, NH3 and NaOH by a novel synthesis process: modification and combination of precipitation
method with spray dryer. The synthesized powders were characterized by different methods such as SEM, TEM,
DTA-TG, XRD, BET and Nanosizer. They represent a spherical granule form with a considerably high specific surface
area of 39-41 m2.g–1 and nano particle size 50-550 nm, 5-300 nm and 26-39 nm according to Nanosizer, TEM and
BET, respectively.
