Özet

Textured ZnO-based varistors were produced by using templated grain growth technique (TGG). Rod-like ZnO particles which used as templates in TGG were synthesized by homogeneous precipitation method from the 0.01 M zinc nitrate and 0.0125 M hexamethylenetetramine (HMT) solutions at 90degreesC. The templates were aligned by tape casting of ZnO based aqueous slurries. A modified tape caster with a comb blade was used for the tape casting process. Texture development in the green and sintered samples was investigated by x-ray diffractometer (XRD) and scanning electron microscope (SEM).
