Simulation of tin penetration in the float glass process
The flat glass produced by the float glass process has a tin-rich surface due to the
contact with molten tin. The penetration of tin into the glass surface is assumed to involve coupled diffusion of stannous (Sn2+) and stannic (Sn4+) ions.
The diffusion coefficients of these ions…[Leggi tutto]
