摘要: Abstract The possibility of using coal fly ash as a silica source for alkali borosilicate glass was investigated. Alkali glasses were prepared from the mixed with 30 wt.% reagents composed Na2O and B2O3 by susceptor-induction heating. Their densities ranged 2.24 to 2.55 g cm−3 decreased amount addition increased. However, Vickers microhardness showed different tendency density since network connectivity improved boron anomaly, which identified nuclear magnetic resonance analysis. product, 15 wt.% Na2O, about 4030 MPa. Furthermore, changes in microstructure consistent those chemical stability toxicity characteristic leaching procedure (TCLP).
