Properties and Structure of Recycled Silicate Glasses

1 Water-Purifying Abiiity of Recycled Silicate Glasses 

ICP analysis showed that the amount of dissolved iron was increased stepwise from 3.6 to 4.7, 12.1, 8.7, and 13.6 mg r after 10 day leachingof ISLS glass with x = 20, as shown in Fig. 31.2 [I I]. Dissolution of Na and Ca, which are weakly bound to the glass skeleton as a network modifier (NWM), also increased from 10.9 to 39.1 mgp and from 

Mossbauer spectra of ISLS glasses with X = (a) 20 and (b) 50. Spectra (1) and (2) were respectively measured before and after the leaching test for 10 days with distilled water. (Reproduced from Ref. 11 with permission of Springer.)
