Glass-melting component

A process for producing a glass melting component composed of refractory metal. A surface zone of the glass melting component is densified at least in sections by application of local compressive stress. As a result the surface zone has its porosity reduced compared to a volume section which is loca...

More Information
Summary:A process for producing a glass melting component composed of refractory metal. A surface zone of the glass melting component is densified at least in sections by application of local compressive stress. As a result the surface zone has its porosity reduced compared to a volume section which is located underneath the surface zone and which has residual porosity.
