Understanding the fundamentals of alkali diffusion in boroaluminosilicate glasses is of critical importance for advanced glass applications, where the alkali diffusivity should be either enhanced or reduced. Here, we investigate the sodium–potassiu

The influence of relative humidity on microhardness, stress intensity, crack resistance, and sub-critical crack growth of an alkaline earth aluminosilicate glass has been studied by Vickers indentation. Quenched and annealed glasses with a wide range

The mechanical properties of glasses are not only determined by their chemical composition, but also by their thermal history, i.e., fictive temperature. In this paper, we consider an alkaline earth aluminosilicate glass composition which has been an

Between December 1998 and April 2001, a submarine basaltic eruption occurred west of Terceira Island, Azores (Portugal) in water depths between 300 and 1,000 m. Physical evidence for the eruption was provided by the periodic occurrence of hot lava �

We propose a model to describe the relationship between the viscosity of a glass-forming liquid and its configurational contribution to liquid state thermal expansion. The viscosity of the glass-forming liquids is expressed in terms of three standard
