Preparation of vitreous multicomponent fluoride films

Vitreous fluorozirconate films were obtained from bulk glass samples previously prepared by fusion. Bulk glass samples were heated between two plates at a constant rate, up to about 10°C above softening point and yet below crystallization onset temperature, under an applied load. Adherence of the fi...

Description
Summary:Vitreous fluorozirconate films were obtained from bulk glass samples previously prepared by fusion. Bulk glass samples were heated between two plates at a constant rate, up to about 10°C above softening point and yet below crystallization onset temperature, under an applied load. Adherence of the films so obtained depended on heating rate and load and was good in vitreous silica, alumina and a series of metallic substrates. The films were stable and scanning electronic microscopy analysis revealed no crystallization. This technique can be applied to any stable fluoride composition.
