Influence of the concentration of phosphatidylcholine (PC) in the solution of 0.5mol?L-1 CaCl2 on the crystal structure of CaCO3 has been studied by means of X-ray diffraction method. When the concentration of PC is below its CMC, the calcite CaCO3 is formed. It advantageous that CaCl2 reacts with Na2CO3 so as to form vaterite CaCO3 in the lipesome composed of PC more than in the water. The arnount of vaterite CaCO3 formed is increased with increase of concentration of PC. But if the concentration of PC is so increased as to form liquid crystal, then the amount of vaterite decreases obviously. The reason for the difference of crystal type formed has been discussed in the paper.
