| 摘 要： | 微孔玻璃是基于分相原理得到的。人们发现,由于Na_2O-B_2O_3-SiO_2系统中同时存在两种形成玻璃网络的氧化物B_2O_3及SiO_2,电价不平衡的[BO_4]四面体趋于获得Na_2O中的游离氧而形成含富Na_2O-Ba_2O_3的相,从而与含富XiO_2相分开,当这种分相玻璃浸于稀盐

| Abstract: | Structure of Na2O-CaO-B2O3-Al2O3-SiO2 system glasses used for the base glasses of large size micro-porous glasses was studied by Raman spectra in the present paper. The results showed that in the case of low content of Na2O(Na2O/B3O3<1),on the substitution of CaO in (SiO3+Al2O3) one non-bridging oxygen atom existing in [SiO4] changed to two non-bridging oxygen atoms. On the other hands, on the substitution of B2O3 in (SiO2+ Al2O3) boron exists in tetraborate, biborate and boron-oxygen ring forms and the non-bridging oxygen atoms in [SiO4] keep constant. The results also show that the glasses made of mineral materials and chemicals have similar Raman spectra but the peak values of the former are a little bit lower than that of the latter. |
