“…This is due to the chemical durability of the glass in synthetic seawater [16]. Previous studies show that, normally B2O3 substituted for SiO2 in network former sites in borosilicate glasses decreases the chemical durability of a glass and also increased the ion released [17].…”

Iron ion from borosilicate glass can be release in seawater depending on the immersion time by the corrosion process. The effect of boron oxide percentage in the quaternary system of glass was studied. The compositions of the glass system [wt.%: (55-x)% SiO2(15-x)% B2O3.25% Fe2O3.5% Na2CO3] where 15%< x <40% have been prepared with the different amount of B2O3(35-55 wt.%) and Fe2O3 with Na2CO3 were fixed. The glass was melting in the alumina crucible for 2 hours soaking time at 1300 °C and cooled to room temperature. The obtained glass was crushed and sieved with yielding a mean size of 2-4 mm. The glass samples in 50 mL synthetic seawater was tested under static condition in 16 weeks to determine the concentration of iron ion and weight loss of the glass samples. The concentration of iron ion was analyzed using UV-Vis Spectrophotometer. The scanning electron microscopy determined the morphology of the sample. From the dissolution studies, it was shown that the concentration of iron ion release was increased with the increasing percentage of B2O3 content. However, the addition of silica oxide was increased the chemical durability of glass system. The percentage boron oxide at 55 wt.% of boron gives the optimum rate of iron ion released in seawater, which is 1.11ppm.

“…According to other studies, the molecular mobility at glass surface is greater than that in the interior, and this has also been experimentally confirmed. In addition, the reaction‐induced crystallization occurs at the surface of a glass when the glass is reacted with its surrounding environments (e.g., some liquids or gases) …”

Reduction‐Induced Inward Diffusion and Crystal Growth on the Surfaces of Iron‐Bearing Silicate Glasses

We investigate the sodium inward diffusion (i.e., sodium diffusion from surface toward interior) in iron containing alkalineearth silicate glasses under reducing conditions around T g and the induced surface crystallization. The surface crystallization is caused by formation of a silicate-gel layer first and then the growth of silica crystals on the glass surface. The type of alkaline-earth cations has a strong impact on both the glass transition and the surface crystallization. In the Mg-containing glass, a quartz layer forms on the glass surface. This could be attributed to the fact that Mg 2+ ions have stronger bonds to oxygen and lower coordination number (4-5) than Ca 2+ , Sr 2+ , and Ba 2+ ions. In contrast, a cristobalite layer forms in Ca-, Sr-, and Ba-containing glasses.

“…Though, a considerable number of recent studies on some tungsten ions doped inorganic glass systems [17][18][19] including some silicate glasses [20,21] are available, most of them are focused on spectroscopic or photochromic studies. The thorough literature survey indicates that still there is a lot of scope to investigate on lithium aluminium zirconium silicate glasses mixed with WO 3 , especially, the dielectric properties.…”
