Moreover, iodine is not only the raw material for producing inorganic or organic compound containing iodine[1], but also for synthesizing several kinds of iodine preparations, sanitizer and pesticides[2].
Reaction Mechanism The decomposing of phosphate by sulfuric acid is a complex process. the chemical reaction equation is as following: Ca5F(PO4)3+10H3PO4 = 3H3PO4+HF+5Ca(H2PO4)2 (1) Ca5F (PO4)3+10H3PO4 = 3H3PO4+HF+5Ca(H2PO4)2 (2) 5Ca(H2PO4)2+5H2SO4 = 10H3PO4+5CaSO4·nH2O (3) 5Ca(H2PO4)2+5H2SO4 =10H3PO4+5CaSO4·nH2O (4) Experimental Experimental apparatus Fig. 1 The schematic diagram of experimental apparatus Experimental materials The fine phosphorite is taken from Wenfu Dressing plant, of which chemical composition is shown in the table 1.

Moreover, they are extremely promising materials for applications in industries, due to their virtues of being high intensity, low density, easy for jointing and so on.
To our knowledge, the macroscopical performance of a material is largely determined by its microstructure features.
