ng> 重質碳酸鈣（重鈣）說明  ng>
ng> 一、重質碳酸鈣的性質及結構ng>
ng>　　重質碳酸鈣簡稱重鈣，是用優質的方解石為原料加工而成白色粉體，它的主要成分是CaCO3，重鈣具有白度高、純度好、色相柔和及化學成分穩定等特點。所以重鈣是工業常用的一種很好的填料。 ng>

ng>1.Introduction:ng>

Calcium Carbonate selects high purity limestone as raw material, is made through process of calcining, chemical reaction, reselection, dehydration, drying and depolymerization. It is adopted the technics of particular multi-selection and secondary depolymerization. It is pure and stable filler whose bulk density is small
