Nitrogen and Argon in Borosilicate Glass: Solubility, Diffusivity, Residual Gas Concentration and Behaviour of Bubbles in Glass Melts, Containing Both Gases
Abstract:Diffusivities of nitrogen and argon in a borosilicate glass were determined with two different
methods: (1) from gas exchange experiments between molten glass and bubbles containing nitrogen
and argon, and (2) from solution rates of nitrogen and argon in glass during saturation experiments.
Between 1200°C and 1580°C the diffusion coefficients of nitrogen and argon yielded the following
equations:
