Abstract

In this work, tin oxides were obtained by the liquid reduction precipitation method and hydrothermal process using $SnCl_2{\cdot}2H_2O$, $N_2H_4$, and NaOH. Tin oxide crystals having different sizes and morphologies could be achieved. The powders were characterized by X-ray diffraction (XRD) and Field Emission Scanning Electron Microscopy (FE-SEM). Depending on the molar ratio of the raw materials, tin oxide crystalline with the spherical and rectangular plate-like shape could be obtained, the crystal phase was SnO and $Sn_6O_4(OH)_4$. And the obtained SnO crystals by a hydrothermal reaction showed various shapes, such as, spherical, plate-like and flower-like architectures depending on the temperature conditions.

본 연구에서는 염화주석, 하이드라진 그리고 수산화나트륨을 원료로 하여 용액환원침전법과 수열반응법을 이용하여 주석산화물 결정을 제조하여, 주요 실험 변수에 의한 결정상 및 형상을 XRD와 SEM을 이용하여 분석하였다. 원료의 몰 비에 따라 구형 및 판상의 주석산화물 결정을 얻을 수 있었으며, 그 결정상은 SnO, $Sn_6O_4(OH)_4$이었다. 그리고 수열반응법에 의하여 얻어진 결정 모양은 온도 조건에 따라 판상 및 꽃 모양의 SnO 결정이 얻어졌다.
