GLASS INDUSTRY

APPLICATIONS

GfE Metalle und Materialien offers vanadium oxide for the manufacture of glass materials with special properties. The absorption of certain wave lengths of the light is adjusted with the degree of oxidation of the vanadium.

On the one hand vanadium is used for the absorption of undesired solar radiation. Pentavalent vanadium has got the property of blocking ultraviolet light. Manufacturers of hollow glass products use this property in beverage bottles for contents sensitive to UV light. Glass for shop windows or fire doors can also be equipped this way.

On the other hand tetravalent vanadium in the glass blocks infrared heat radiation. For example, this effect is used in automobile windscreens or in glass ceramics for modern stove cooking tops.

For these fields of application GfE Metalle und Materialien provides vanadium pentoxide to prepare the batch for the glass melt.
