The distribution of silicate species in silicate melts is analyzed using the techniques of conventional polymer chemistry. The structure of a melt is dominated by the SiO 4 monomer at low silica compositions. With increasing SiO 2 , the silicate species polymerize forming larger branch and ring structures. Infinitely branched species have a high probability of forming once 1/3 of the singly bonded oxygens of the silicon atoms become doubly bonded to two silicon atoms. In most binary silicate melts, this point is reached at mole fractions N siO 2 between 0.28 and 0.44. The extent of polymerization of a melt can be expressed as a constant, K . This constant can, in turn, be correlated to the field strength of the cation that is added as an oxide. Cations of high field strength form the most polymerized melts. These highly polymerized melts are characterized by liquid immiscibility at high silica compositions.
