摘要
Abstract
Double carbonation route for the synthesis of hydrophobic chain-like nanometer calcium carbonate was studied. In the process, citric acid and cetyl acid were used as an organic substrate to induce the nuclea-tion and modify the surface of calcium carbonate separately. The operating parameters such as temperature and the concentration of the organic substrate were varied to study their influences on the active ratio and contact angle of calcium carbonate particles. The products were characterized by transmission electron microscope ( TEM) , X-ray powder diffraction ( XRD) , Fourier transform infra-red ( FTIR) and thermo gravimetric analysis (TGA).The results show that hydrophobic chain-like nanometer CaCO3 crystals can be obtained in the presence of citric acid and cetyl acid. Whereas, only cubic CaCO3 crystals can be obtained without citric acid and cetyl acid.关键词
