Research and development activities, waste fixation program. Quarterly progress report, July--September 1973

Description: The aim of the melt development program is to produce meltformed ceramic products that have the optimum combination of physical properties for the fixation of radioactive wastes. Depending on thermal treatment many of the ceramics can be in either a glassy or a microcrystalline form. Laboratory and nonradioactive pilot plant tests are being conducted to evaluate both forms. Both PW-4b and PW-6 waste compositions were successfully solidified into borosilicate glass in the development spray solid… more

Screen-printing of 1720 and 7059 glass insulating bonds for the radioisotopic thermoelectric generator

Description: As part of the RTG fabrication sequence, Si/Ge and Si/Ge-glass substrates are coated with Corning 1720 and 7059 glass by a screen-printing process. A slurry of glass, pine oil, and terpinol is printed, followed by a burnout of the organic matter in oxygen at 500 deg C. It has been determined from overall fabrication considerations that there should be sufficient glass present to yield a fused-glass thickness of 1.2 to 1.4 mils. Glass content of the slurry, screen size, squeegee pressure, and br… more

Discussion of glass-water interactions. Physical and chemical processes

Description: Leaching data for the alkali and alkaline earth silicate glasses are reviewed. The mechanism is based on the structure being dominated by SiO/sub 4/ tetrahedra forming a random network by sharing their corners (bridging oxygens). Dealkalization of the glass is initiated by the proton adsorption on to the glass surface. The intermediate to long-term interaction is characterized by a steady state between dealkalization and lattice attack such that the leached zone maintains a constant thickness. … more

Lattice vibrations in noncrystalline solids

Description: The specific heat of noncrystalline solids differs from that predicted by the Debye model by amounts much larger than is known for crystalline solids. This deviation is most pronounced at temperatures below 1 deg K. Near 0.1 deg K. the experimental specific heat approaches a linear temperature dependence and is up to 30 times larger than predicted by the Debye model. This paper describes Brillouin scattering experiments, and also measurements of the thermal conductivity in thin glass fibers. Th… more

Analytical studies of ancient Egyptian glass

Description: Neutron activation analysis and emission spectroscopy were used to analyze ancient Egyptian glass. The emission spectroscopic method for determining Li, Na, K, Rb, Mg, Ca, Sr, Ba, B, Al, P, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zr, Ag, Sn, Sb, Pb, and Bi is described in the appendix. Neutron activation was used to determine Na, K, Rb, Ba, Sc, La, Ce, Eu, Lu, Hf, Th, Ta, Cr, Fe, Co, and Sb by a method described by Tobia and Sayre at the conference. (DHM)

Improved quality GSC-4 sealing glass

Description: A glass commonly used to make graded seals between fused silica and higher-expansion glasses, General Electric Company GSC-4, was remelted to obtain higher quality glass than is available commercially. Remelting the commercially available glass cane in a platinum crucible at 1700 deg C for periods of 40 to 60 hours produced a homogeneous glass free of crysinlline inclusions and bubbles. During this melting, water was evolved and some constituents were lost from the surface layer. The bulk compo… more

A Comparative Investigation of the Application of Photographic Images to Glass by Screen-Process Enamel Ink, Screen-Process Glass Etching, and Transfer-Key

Description: The problem with which this comparative investigation is concerned is the application of a photographically derived image to glass. The image used originated from an ordinary thirty-five-millimeter color slide. This slide, through photographic darkroom manipulation, was translated into thirty individually different, black and white films of four-by-five-inch size. Selected films were then enlarged onto eleven-by-fourteen-inch, Kodalith film. These enlarged films were contact exposed to Ulano's … more

Properties of Glasses in Some Ternary Systems Containing BaO and SiO2

Description: Report discussing the glass forming regions in six ternary oxide systems containing BaO, Si02, and a third oxide. The properties of the resulting glasses were measured and the results reported. The data on refractive indices, dispersions, and specific volumes were evaluated by computer methods in an attempt to identify "substructures" containing the cations present in the glasses.
