Molybdenum glass tank reinforcements
In the glass melt tank, the refractory bricks are exposed unprotected to the aggressive glass melt. The result: Corrosion which can significantly reduce the service life of the glass melt tank. Platinum and molybdenum are the only metals that are able to withstand the high temperatures and chemical corrosion caused by the glass melt. Platinum is very expensive - molybdenum is the economical, high-performance alternative.
Glass wool and glass fiber are manufactured at temperatures of over 1 600 °C (2912 °F). During the production process, the liquid melt passes through outflow nozzles made of molybdenum or tungsten. The melt is then either blown or spun to create the finished product. It is essential that the molten stream is precisely dosed and perfectly centered if a high-quality finished product is to be achieved. We make this possible with our temperature-resistant molybdenum and tungsten nozzles. With their iridium and rhenium inserts these nozzles combine excellent corrosion resistance with a long service life. To make sure our nozzles last even longer, we have developed a special technology for joining the small precious metal tubes to the body of the nozzle.
