| Abstract: | In this paper,an inverse microemulsion was prepared with a mixed solution of calcium chloride and ammonia as the aqueous phase,polyoxyethylene octyl phenol ether-10(OP-10)as the surfactant,n-octanol as the co-surfactant,cyclohexane as the oil phase.Micro/nano calcium carbonate was prepared by passing CO 2 gas into it,and discus-shaped micron calcium carbonate was prepared.Scanning electron microscope(SEM),X-ray powder diffraction(XRD)and Fourier transform infrared spectroscopy(FTIR)were used to characterize the morphology and crystal structure of micrometer calcium carbonate.The formation mechanism of discus-shaped calcium carbonate was preliminarily discussed. |
| Keywords: | Discus-shaped calcium carbonate reverse microemulsion co-surfactant,mechanism |
