Abstract Silicate melts are special fractal dimension system that is metastable state of near-way order and far-way disorder. In this paper,the size of nanometer aggregation structure and the frequences of phonon vibration like mode in the low dimension silicate series(CaO-Al2O3-SiO2 and Na2O-Al2O3-SiO2 series) synthesized via high temperature melting and sol gel methods were measured by means of small-angle X-ray scattering (SAXS), low wavenumber Raman spectrum(LWRS) and high temperature Raman spectrum(HTRS in situ measuring). The nanometer self-similarity aggregation structure(it’s size is about a few nm to a few tens nm) and phonic phonon vibration like modes of low temperature silicate gel, high temperature silicate melts and it’s quenching glasses phases were obtained. So a quantitative method by HTRS for measuring the aggregation size in the high temperature melts was established. The results showed that the aggregation size of the silicate melts is smaller at high temperature than at room temperature and the number of bridge oxygen in one Si—O tetrahedron in network structure units is decreasing at high temperature. This study work provides important theory and information for deliberating geochemistry characteristic, crystallization & evolution of natural magma and enhancing performance of low dimension silicate matelials.
