Abstract

본 연구는 Al 금속으로부터 염화수은, 요오드, 요오드화 수은, 염화제이철 촉매 조건하에서 알루미늄 이소프로폭사이드를 합성하였으며, 합성한 알루미늄 이소프로폭사이드를 이용하여 숙성과 해교과정을 통해 미세구조와 표면특성이 조절된 코팅용 알루미나[γ-AlO(OH)] 졸 용액을 합성하였다. Al 금속의 용해반응 시간은 사용된 촉매에 따라 I2

Using Al metal and isopropyl alcohol, aluminum isopropoxide was synthesized under various catalysts such as mercuric chloride, iodine, mercuric iodide and ferric chloride. The solution reaction time of Al metal was increased according to catalysts, as an order of I2
