Nucleation in Photosensitive Gold Ruby Glass

The numbers of gold particles in a gold ruby glass were calculated as a function of irradiation time, nucleation and irradiation temperature, and cerium concentration. Photonucleation in Ce-containing glasses and nucleation by X rays in glasses without cerium were similar, suggesting that cerium was not directly involved in nucleating the gold particles. The results were consistent with nucleation by trapped photoelectrons. Temperature of irradiation and cerium concentration influenced production and recombination of the trapped electrons. A decreased number of nuclei as the nucleation temperature increased probably resulted from recombination of the trapped electrons.     

Ruby Glass Produced in a Pt-Au Crucible

Polarographic Analysis for Antimony in Glass

Antimony, usually added as a fining agent in a concentration range of about 0.2 to 2.0% Sb₂O₃, can be determined readily in many types of glass with a polarograph. Interfering elements are seldom encountered in common glass compositions, so chemical separations are not necessary. The mean difference between chemical and polarographic analyses for twenty-one glasses covering soda-lime, borosilicate, lead, and barium compositions is about 0.02% Sb₂O₃.     

Evaporation of Antimony Trioxide from Glass Melts

The transpiration method was used to study the evaporation of Sb₂O₃ from a glass melt with the composition 70SiO₂·15K₂O·15CaO·MgO (in wt%) at 1200° to 1300°C. The glass contained about 0.9 wt% Sb₂O₃. Assuming the monomer Sb₂O₃ is the species of evaporation, the saturation vapor pressures could be calculated with ΔH_V=218±20 kJ·mol⁻¹ and ΔS_V=128±10 J·mol⁻¹·K⁻¹.
