摘要
热处理的浸出行为分离的含铁钠硼硅玻璃的成分范围内8 Na 2 O·2(22 -х)B O·70 sio 2·х菲2 O 3,х变化从0.3到10 mol. %,和(8 - x) Na 2 O∙∙22 B 2 O 70 sio 2·x菲2 O 3,х变化从2到6 mol. %, 3 m盐酸水溶液在沸腾,进行了研究。结果表明，与不含fe2o3的玻璃相比，fe2o3的引入提高了这些相分离玻璃的化学耐久性、孔隙率和平均孔径值，但降低了基于fe2o3的多孔玻璃的比表面积。确定了适于生产多孔玻璃的组合物。DOI: http://dx.doi.org/10.5755/j01.ct.67.1.14800
Leaching of phase-separated glasses in the Na2O-B2O3-SiO2-Fe2O3 system
The leaching behavior of heat-treated phase-separated iron-containing sodium borosilicate glasses within the range of compositions of 8Na 2 O·(22 – х )B 2 O 3 ·70SiO 2 · х Fe 2 O 3 , where х varies from 0.3 to 10 mol.%, and (8 – x )Na 2 O∙22B 2 O 3 ∙70SiO 2 · x Fe 2 O 3 , where х varies from 2 to 6 mol.%, in the 3M aqueous HCl solution at boiling, was studied. It has been shown that the introduction of Fe 2 O 3 in these phase-separated glasses increases their chemical durability, the values of porosity and the average pore diameter, but reduces the specific surface area in the porous glasses based on them, compared with glass without Fe 2 O 3 . The compositions suitable for producing porous glasses were determined. DOI: http://dx.doi.org/10.5755/j01.ct.67.1.14800
