The stress-optical coefficients of binary and ternary borate glasses were measured and the factor (p·q), where p and q are the Neumann strain-optical coefficients, was determined. As a modifier oxide was added to B2O3 glass, the stress-optical coeff

The viscoelastic properties of phosphate and borate glasses at and below the transition temperature (T g ) were investigated using the dynamic viscoelastic measuring method. The viscosity in these glasses was found to increase with decreasing tempera

It is known that fly ash from municipal waste incinerators is particularly problematic because it contains a significant concentration of heavy metals and chloride. One of the methods for treating chloride is to entrap it in a glassy slag, which is p

Redox reaction of platinum ion in 50PbO⋅50SiO2 (molar ratio) melt was analyzed electrochemically using cyclic voltammetry and chronopotentiometry. The platinum ion in the melt was reduced at around -250mV (Pt2+/Pt0), in the temperature range 800°C

In order to reveal the interface reaction mechanism between platinum and 50PbO⋅50SiO2 glass melts, the redox reaction of platinum was studied electrochemically by cyclic voltammetry with platinum electrodes between 800°C and 1000°C. On cyclic vol

Transparent glass-ceramics, in which the crystalline phase has basically a face centered cubic structure, have been prepared in the system K 2 ONb 2 O 5 TeO 2 , and a second harmonic generation (SHG) is observed. The second harmonic intensity i

A new adhesion process of glass to metal was developed based on the redox reaction without oxidation of the metal surface. PbO-based glasses were strongly adhered to nickel metal at low temperature (400–500 °C) in a low-oxygen atmosphere (< 0.1 p.
