摘要：
Infrared and Raman spectroscopies have been used to analyze two series of sodium silicoborate glasses with 10% and 20 % of Na(2)O. The obtained results are in accordance with those found in literature when using Raman and Infrared spectroscopies, however here it has been analyze in more detail the Polimerization Index (IP) of both systems. It has been observed that IP decreases with B concentration except for low B content glasses. This result has been assigned to an incomplete melting of Such glasses due to the high temperatures needed to obtain well-melting glasses. Finally, it has been analyzed the BO(4)/BO(3) ratio as a function of the Na(2)O concentration, showing that as it would be expected the high BO(4) concentration appears when the Na(2)O concentration is between 0.3 - 0.4 in moles.
