A Study on the Synthesis of Zinc Oxide Nanoparticles by Experimental Method in MCP Process

Abstract

ZnO 나노 입자가 진동밀 공정에 의해서 합성되었다. 진동밀 공정에 의해서 제조된 비정질 ZnO 파우더는 NaCl을 제거하기 위해서 세척되었고, 약 300~500℃ 근방에서 2시간 동안 소성되었다. 본 연구에서는 통계적 실험 계획법이 사용되었으며, ZnO 나노 입자의 입경과 입도 분포는 밀링 시간과 볼과 파우더의 질량비에 의존함을 알 수 있었다. 결과적으로 평균 입경 약 100 nm 크기를 지닌 ZnO 나노 입자가 합성되었다.; Zinc oxide (ZnO) nanoparticles were synthesized by vibrating milling process. Amorphous ZnO powders prepared by the milling process were washed with water to remove NaCl, and then the powders were sintered at 300~500℃ for 2 hrs. In this work, statistical experimental design method was used and it was found that the particle size and size distribution of ZnO nanoparticles were dependent on the milling time and mass ratio of ball to powder. Therefore, ZnO nanoparticles with 100 nm of mean crystallite size were obtained.
