INVESTIGATION ON PHYSICAL AND ELECTRICAL PROPERTIES OF THE SiO2-ZnO NANOCOMPOSITE AT DIFFERENT COMPOSITION MIXINGS
<p>Physical and electrical properties of The SiO<sub>2</sub>-ZnO mixing at different compositions were investigated. The experiment used simple mixing method at the sintering temperature 600<sup>o</sup>C. It was used the composition mixing ratio of SiO<sub>2</sub>:ZnO ie. 0<strong>:</strong>10; 7<strong>:</strong>3; 5<strong>:</strong>5; 3<strong>:</strong>7; and 10:0 (%Wt)<sub>. </sub>Based on X-Ray Diffraction (XRD) results, it obtained that a new phase in each sample was not formed even though having different diffraction peak. The mixing ratio of SiO<sub>2</sub>: ZnO nanocomposite (7:3 %wt) had the biggest grain size (77,92 nm), the highest dielectric constant (3.00E+05) and the smallest conductivity (0,726549 (Ωm)<sup>-1</sup>). On the other side, the mixing ratio of SiO<sub>2</sub>: ZnO nanocomposite (5:5 %wt) had the smallest grain size (35.42nm), dielectric constant (3.00E+2) and the highest conductivity (25.36729 (Ωm)<sup>-1</sup>). It can be concluded that the difference of composition ratio offered the change on both physical and electrical properties of SiO<sub>2</sub>-ZnO nanocomposite. </p>
