Zirconium dioxide (ZrO₂) nanoparticles have been synthesized via microwave assisted method. The structural analysis was carried out using X-ray diffraction. It showed that the ZrO₂ nanoparticles exhibited monoclinic structure. The morphological studies revealed that the particles were spherical in structure and slightly agglomerated. The ZrO₂ product was investigated by FT-IR, UV, SEM and microbial activity studies.
