초록

최근 수산화마그네슘은 비독성, 비부식성 및 열적 안정성 같은 우수한 특성에 의해 다양한 분야에 적용된다. 본 연구는 황산마그네슘과 염화마그네슘 그리고 질산마그네슘을 전구체로 하고, 수산화나트륨과 암모니아수를 알카리원으로 하여 상온에서 침전법을 통해 플라워 그리고 플레이크 형의 수산화마그네슘을 합성하였다. 전구체의 종류 및 합성 변수에 따른 수산화마그네슘의 형태와 크기 영향 확인하였다. 수산화마그네슘의 형상은 마그네슘전구체와 알칼리원에 의존한다. 생성된 플라워형 입자의 평균 크기는 대략 $1{\mu}m$ 그리고 플레이크형의 입자는 20 ~ 50 nm의 크기를 갖는 것을 확인하였다. 합성된 수산화마그네슘의 특성은 XRD, FE-SEM, FT-IR, EDS, PSA 그리고 TG를 통해 확인하였다.

Recently, magnesium hydroxide ($Mg(OH)_2$) has many applications in various field, due to its outstanding characteristics such as a nontoxic, noncorrosive and thermal stable properties. In this study, different shapes of flower and flake type magnesium hydroxide were synthesized by precipitation method at room temperature using $MgSO_4$, $MgCl_2$ and $Mg(NO_3)_2$ as magnesium sources, NaOH and $NH_3$ as alkaline sources. Influence of synthesis on the morphological characteristics, sizes and shapes of magnesium hydroxide particles, was investigated, such as different precursors and parameters. The shape of magnesium hydroxide depend on magnesium and alkali sources. Average size of flower particle had about $1{\mu}m$, and flake had about 20 ~ 50 nm. The synthesised magnesium hydroxide groups were characterized by XRD, FE-SEM, FT-IR, EDS, PSA and TG.
