Abstract

$CaCO_3$ was applied in various industries including rubber, plastics, paint, paper, food additives, and acid neutralizer, etc., owing to its excellent physical and chemical characteristics as well as various appearances of crystals and many reserves. In particular, research on controlling the structure and shape of $CaCO_3$ has attracted considerable attention recently, because the whiteness and physical characteristics of $CaCO_3$ depend on the size and shapes of the particles. In this study, $CaCO_3$ was synthesized using $CaCl_2$ and $(NH4)_2CO_3$, which has multi-shapes and structures, using a self-assembly method with a hydrothermal method. The structure and morphology of the $CaCO_3$ could be controlled by adjusting the pH and precursor concentration. In particular, the pH adjustment appeared to be a critical factor for the morphology and crystal form. In addition, the calcite and cubic shape were obtained at pH 7, while the mixed calcite, aragonite structure, and rod shapes appeared at pH 7 and over. Through an analysis of the particle formation process, the formation of the calcium carbonate particles was confirmed. The physicochemical properties of the synthesized $CaCO_3$ were analyzed by SEM, XRD, EDS, FTIR, and TG/DTA.

탄산칼슘은 뛰어난 물리 화학적 특성, 다양한 결정성, 많은 매장량 등으로 인한 경제성 등 때문에 고무, 플라스틱, 종이, 식품 첨가제 및 중화제 등 여러 분야에 걸쳐 응용되고 있다. 특히, 탄산칼슘의 백색도 및 물리적 특성은 입자의 크기 및 형상에 의존하기 때문에 구조 및 형태를 조절하는 연구가 최근 주목 받고 있다. 본 논문은, 수열합성법 및 자기조립법을 이용하여 염화칼슘과 탄산칼슘을 이용해 다양한 형상과 결정구조를 갖는 탄산칼슘을 합성하였다. 탄산칼슘의 구조 및 형태는 pH 및 전구체의 농도를 조절함으로써 제어할 수 있으며, 특히 pH 조절은 탄산칼슘의 형상 조절 및 결정성 변화에 중요한 요인으로 나타났다. 다양한 조건을 통한 실험 결과, 칼사이트 결정형을 가지며 큐빅 형상을 지닌 탄산칼슘은 pH 7에서 나타났고, 아라고나이트와 칼사이트상을 동시에 가지며 로드형상을 갖는 탄산칼슘 입자는 pH 7 이상에서 나타났다. 연구 결과 입자의 생성과정 분석을 통해 탄산칼슘 입자의 형성 과정을 확인할 수 있었다. 탄산칼슘의 물리 화학적 특성은 SEM, XRD, EDS, FTIR 및 TG/DTA를 통해 확인하였다.
