Dielectric Properties of Willemite Zn2SiO4 Nano Powders by Sol-gel Method

Nano particles of willemite, α-Zn2SiO4 have been prepared by a sol-gel method. Transformation of crystal phases in nano powders has been characterized by XRD and SEM. Dielectric properties such as dielectric constant (ɛʹ) and dielectric loss (ɛ”), and conductivity (ζac) related results have successfully been studied. The XRD profiles have shown that a sample sintered at 950oC (optimized) has displayed well defined features. The results thus obtained in the present work, are quite encouraging and found these materials could be suggested as novel materials with potential applications.
