| 초록 | Precipitated calcium carbonate is one of the most versatile mineral fillers and is consumed in an wide range of products including paper, paint, plastics, rubber, textiles, sealants, adhesives, and printing ink and can be produced by several methods. Calcium carbonate has three isomorphism; vaterite, aragonite and calcite, with numerous variations of morphology in the natural mineral or organism. Formation process of vaterite in the reaction of system Ca(OH)2-CH3OH-H2O-CO2 were investigated by measuring the electrical conductivity, Ca2+ ion concentration, pH in the slurries, and by means of X-ray diffraction and electron microscopic observation. It was clearly established that content of Fe2O3 is important variable in whiteness and Na2O is important variable in vaterite's yield. We suggest that vaterite particles of whiteness over 92 is made in below 0.03% of Fe2O3 and yield over 50% is made in below 1% of Na2O |
