    Abstract: This ultralow-loss glass is characterized in that high purity silica glass contains 1 to 500 wt.ppm of at least one network modifying oxide. It is assumed that the network modifying oxide appropriately loosens the tetrahedral network structure of silica and hence Rayleigh scattering is decreased. Examples of the network modifying oxide include Na.sub.2 O, K.sub.2 O, Li.sub.2 O, MgO, CaO, and PbO. Since Rayleigh scattering losses are minimal in comparison with those of high purity silica glass, this impurity-added silica glass is excellent as a base material of a glass fiber for a long-distance transmission.

    Abstract translation: 这种超低损耗玻璃的特征在于,高纯度二氧化硅玻璃含有1至500重量ppm的至少一种网络改性氧化物。 假设网络修饰氧化物适当地松散二氧化硅的四面体网络结构,因此瑞利散射降低。 网络改性氧化物的实例包括Na 2 O,K 2 O,Li 2 O,MgO,CaO和PbO。 由于与高纯度二氧化硅玻璃相比,瑞利散射损失最小,所以这种添加了杂质的石英玻璃作为用于长距离传输的玻璃纤维的基材是优异的。

    Abstract: This invention relates to the immobilization of toxic, e.g., radioactive materials, internally in a silicate glass or silica gel matrix for extremely long periods of time. Toxic materials, such as radioactive wastes containing radioactive anions, and in some cases cations, which may be in the form of liquids, or solids dissolved or dispersed in liquids or gases, are internally incorporated into a glass matrix, having hydrous organofunctionalsiloxy groups, e.g., hydrous aminoalkylsiloxy or carboxyorganosiloxy, bonded to silicon atoms of said glass and/or hydrous polyvalent metals bonded to silicon atoms of said glass through divalent oxygen linkages or otherwise immobilized therein, by a process which involves the ion exchange of said toxic, radioactive anions with hydroxyl groups attached to said organofunctionalsiloxy groups or with hydroxyl groups attached to the hydrous polyvalent metal. Thereafter, the resulting glass now characterized by a distribution of internally bonded or immobilized, toxic, radioactive anions can be packaged in suitable containers, and disposed of as by burial, and/or they can be sintered to collapse the pores thereof to disposal or for producing useful radiation sources. The porous glass or a porous silica gel having said silicon-bonded organofunctionalsiloxy groups and/or said hydrous polyvalent metal oxy groups, the pores of said glass or silica gel remaining open and uncollapsed, can be used advantageously as a backfill for an underground radioactive waste burial site and as overpack in the waste disposal container. Also included is a novel method for bonding the polyvalent metal to the porous silica glass or gel by substituting the protons of the silicon-bonded hydroxyl groups thereof with an alkali metal or ammonium cation followed by displacement of said cation with the non-radioactive polyvalent metal cation.

    Abstract: PURPOSE: An ultra-low loss glass having low Rayleigh scattering loss is provided which is excellent as the mother material of a glass fiber for long distance forwarding by doping impurities to a high purity glass. CONSTITUTION: An ultra low loss glass is obtained by doping at least one metallic oxide selected from Na2O, K2O, Li2O, MgO, CaO, PbO of 1- 500 wt, ppm to a high purity glass which loosen the tetrahedron network structure of silica. The resultant glass is used for the optical fiber due to low Rayleigh scattering compared with a pure silica glass.
