“…24,25 Gibbs et al have studied the system Li 2 O-MgO-MgF 2 -SiO 2 within the temperature range of 1350 to 1450 C and identified a mixture of layered silicate and protoamphibole. 26 Following work by Barrer and Jones, Corning Glass, Inc. company synthesized Li-hect in the 1970s with a chemical composition of [Li 0.56 ] inter [Mg 2.44 Li 0.56 ] oct [Si 4 ] tet O 10 F 2 and a cation exchange capacity of 122 meq per 100 g. 27 Unfortunately, this material is not available any longer.…”

Melt-synthesis yielded lithium-fluorohectorites (Li-hect(x)) with variable layer charge (x = 0.4, 0.6, 0.8, 1.0). Counterintuitively, both tactoid diameter and intracrystalline reactivity increased concomitantly with increasing layer charge. This way hectorites with very large diameters were obtained (d(50%) = 48 μm) that nevertheless still spontaneously delaminate when immersed into water and nano-platelets with huge aspect ratios (>10 000) are formed. Melt-synthesis of Li-hect(x) has been performed in an open glassy carbon crucible allowing for easy scaling to batches of 500 g. These unprecedented huge aspect ratio fillers promise great potential for flame retardants and barrier applications.

“…A number of researches related to low melting glass have been reported [1][2][3][4][5][6]. In those previous works, heavy metal species like lead with a bulky atomic volume was added to decrease the density of siloxane bondings.…”

“…Technically, viscous flow of glass needs to be measured in a way quite different from those adopted in cases of measurements of normal viscous liquids. For example, we can find recent works which report viscous flow measurements of glass [1,[11][12][13]. In order to use temperature-dependent viscous flow of phenyl glass as a quantitative measure, the activation energy should be obtained by the Arrhenius plot as seen in previous works [14,15].…”
