초록
침전법, 수열 반응법, 리간드 보조법을 사용하여 다양한 형태의 BaCO3 결정을 합성하였다. 수용액에서 Ba(NO3)2 과 Na2CO3를 단순 침전시키면 불규칙한 입자 형태의 BaCO3 마이크로 결정이 얻어졌다. 수열 반응으로 Ba(NO3)2와 urea를 반응시켜 육각형 막대 피라미드 형태의 BaCO3를 합성하였으며, 리간드 보조 수열 반응법을 사용하여 육각형 막대형의 BaCO3를 합성하였다. 리간드 농도가 증가 할수록 BaCO3 육각형 막대의 종횡비가 증가하였다
Abstract
BaCO3 crystals with various morphology were prepared using precipitation, hydrothermal and ligand-assisted methods. An irregular structure of BaCO3 microparticle was obtained by simple precipitation method from Ba(NO3)2 and Na2CO3 in aqueous solution. Hexagonal pyramidals of BaCO3 were synthesized using a hydrothermal method between Ba(NO3)2 and urea. Hexagonal rods of BaCO3 were also synthesized using the ligand-assisted hydrothermal method. The aspect ratio of BaCO3 hexagonal rods was increased with the concentration of ligand.
