    摘要: A process for producing an optical glass fiber from crystal-glass phase material. In one embodiment, the process includes the step of providing a molten crystal-glass phase material in a container, wherein the temperature of the molten crystal-glass phase material is at or above the melting temperature of the molten crystal-glass phase material, Tm, to allow the molten crystal-glass phase material is in liquid phase. The process further includes the step of cooling the molten crystal-glass phase material such that the temperature of the molten crystal-glass phase material, T1, is reduced to below Tm to cause the molten crystal-glass phase material to be changed from the liquid phase to a viscous melt. Moreover, the process has the step of pulling a glass fiber of the crystal-glass phase material from the viscous melt, wherein T1 satisfies the following relationship: Tv

    摘要: Soluble chalcogenido clusters together with transition metal ions and main group elements are shown to provide gels having interconnected, open frameworks. Following supercritical drying with liquid carbon dioxide, the chalcogels may be converted to aerogels. The aerogels possess high internal surface areas with a broad pore size distribution that is dependent upon the precursors used and the aging conditions applied. Some of the gels are encompassed by formulas such as M4[M′4Qx]n, M4[M′2Qy]n, M4[M′Qx]n, M3[M″Qx]n, or Me2[M′″Qx]n, where M is a divalent, trivalent, or tetravalent metal ion; M′, M″, and M′″ are typically Ge, Sn, P, As, Sb, Mo, or W; and Q is typically S, Se, or Te. Methods of preparing the chalcogenido clusters are also provided.
