While avoiding the disadvantages of the screen printing technique employed until now, the invention provides a shaping tool ( ) with a structured surface for creating structures on glass ( ) which, in an economical way, makes it possible to form high-precision microstructures by local heating of the region of glass to be structured. The shaping tool ( ) has a rolling cylinder ( ) including a metal hollow cylinder ( ) and a shaping sheet ( ) secured in a surface contact to it, as well as a continuous shaft ( ) for continuously driving the rolling cylinder ( ) via drivers ( ) coupled to the hollow cylinder ( ). Between the shaft ( ) and the hollow cylinder ( ), an electric heater ( ) for targeted local heating of the glass during structuring is disposed in an electrically insulated fashion. The electric heater ( ) is advantageously thermally insulated from the shaft ( ) with a ceramic cylinder ( ).

Shaping tool with a structured surface for producing structures on glass, and the application thereof for structuring channel plates

Structural units which come into contact with glass melts and ceramic melts are exposed to strong corrosive attack. Molybdenum is a known material for glass melt electrodes but it is not usable for the majority of highly corrosive glass and ceramic melts. The use of a special molybdenum and/or tungsten alloy as the material for the structural unit reduces corrosion even in the case of contact with highly corrosive glass and ceramic melts.

Structural units for glass melts made from a molybdenum/tungsten alloy

The invention relates to an oxidation inhibitor coating for high-melting metals selected from the group of molybdenum, tungsten, tantalum and niobium and/or alloys thereof. The oxidation inhibitor coating comprises 1 to 14% by weight boron, 0.1 to 4% by weight carbon and the balance silicon.
