Research on properties and structures of borate glasses using phase diagram method II. NMR studies of glass structures in the systems Li_2O-B_2O_3-SiO_2, CdO-B_2O_3-GeO_2 and Li_2O-B_2O_3-TeO_2

Based on the principle of phase diagram, the present authors have calculated the values of NBO4 by computer in glass systems Li2O-B2O3-SiO2, CdO-B2O3-GeO2 and Li2O-B2O3-TeO2, and compared the calculated values with the experimental ones, and put forward a new quantitative structure model of glass. We suggest that the structure of glass resembles the structure of the related crystalline. A multicompo-nent glass can be regarded as the melted mixture of some nearest congruent melting compounds in phase diagram, and the contents of the nearest congruent melted compounds are allotted by level rule, namely the phase diagram model we put forward some simple assumptions and make some oorraction for ternary systems' which do not have perfect phase diagrams.
