摘要：
The present invention provides a grainy material which comprises the following components: (i) at least 50wt% of solid water-insoluble mixed metal compound when the weight of the grainy material is taken as a reference, the mixed metal compound can combine with microcosmic salt of the formula (I): M<；II>；1-xM<；II>；x(OH)2A<；n->；y*zH2O (I), in the formula M<；II>； is magnesium, calcium, lanthanum and cerium； M<；III>； is iron at least； A<；n->； is at least one n-valence anion； x is the summation of ny； 0<；x<；=0.67, 0<；y<；=1, and 0<；=z<；=10； (ii) non chemically combining water between 3 to 12wt% of the weight of the grainy material is taken as a reference； and (iii) excipient no larger than 47wt% of the weight of the grainy material is taken as a reference.
