Preparation of Rapidly Quenched Glasses in Pseudobinary Systems Composed of Lithium Ortho‐Oxosalts

Twin‐roller quenching was attempted for 15 pseudobinary systems combining two chosen from the lithium ortho‐oxosalts, i.e. Li 3 BO 3 , Li 4 SiO 4 , Li 4 GeO 4 , Li 3 PO 4 , Li 2 SO 4 , and Li 2 WO 4 . Glassy flakes were obtained in almost all systems. Glass formation was easier in systems containing large amounts of Li 3 BO 3 or Li 2 WO 4 compared to those containing Li 4 GeO 4 or Li 3 PO 4 . Glass transition, crystallization, and liquidus temperatures were determined. Infrared spectra revealed that the glasses consisted of Li + ions and discrete ortho‐oxoanions only .
