| 제목 | Effects of PAA additive and temperature on morphology of calcium carbonate particles |
| 초록 | Calcium carbonate particles with various shapes were prepared by the reaction of sodium carbonate with calcium chloride in the absence and presence of a polyacrylic acid (PAA) at 25°C and 80°C, respectively. The as-prepared products were characterized with scanning electron microscopy and X-ray diffraction. The effects of temperatures and concentration of PAA were investigated. The temperatures and concentration of PAA are important parameters for the control of morphologies of CaCO3. Various crystal morphologies of calcite, such as, plates, rhombohedras, rectangles, ellipsoids, cubes, etc. can be obtained depending on the experimental conditions. This research may provide new insight into the control of morphologies of calcium carbonate and the biomimetic synthesis of novel inorganic materials. |
