　　In this paper, precipitated calcium carbonate(GCC) was modified by starch with the aid of sodium stearate and sodium hexametaphosphate.The property and using performance of modified GCC and GCC were studied.The results showed that the brightness, opacity, Zeta potential, and particle size distribution of GCC were changed after the modification by starch.The strength properties of paper added with modified GCC are much better than those added with unmodified GCC.
