Thermal plasma processing of spherical ZnO nano powders

Nano Zinc oxide (ZnO) is gaining more importance and its demand is keep increasing in recent decades because of its potential applications in energy, optoelectronic and sensor fields. To address this issue, the bulk synthesis of nano ZnO is demonstrated in the present article by the thermal plasma processing. Nano sized ZnO spherical particles of size 3 – 25 nm evidenced by transmission electron microscopy (TEM) have been synthesized from micron...
