| Abstract: | In this paper, the author presents a detailed study of the component, molecular networkstructure and degree of broken bond of glasses phases in the Al2O3-SiO2 system and the Na2O-K2O-Al2O3-SiO2 system by using an electron probe, Laser Raman Molecular Microprobe and high temperatureand high pressure experiment etc. The obtained conclusions are as follow:1.No matter whether it is a glasses phases of geological body or silicates glasses phases in industrymaterial, its molecular network structure is consisted of six models. They are Monomer[SiO4], Dimer[Si2O7], Ring and chain [SiO3], Sheet[Si2O5], Frame network[Si4O9]and Pure frmae network [SiO2].2. A study of molecular network structure in glasses phases is conducive to reappear physical-chemicalhistory of natural magmatic crystallization and development. This has important significance for investigatingforming ore conditions and enhancing performance of industry silicate materials. |
