Tungsten & Molybdenum
Products for Quartz Production
T&D Materials manufactures and supplies premium quality tungsten and molybdenum products for quartz glass production and quartz material.
Quartz glass or quartz material is produced in special high-temperature furnaces due to the high melting temperatures (approx. 2000°C). The heart of such a furnace consists of a melting crucible, which is continually filled with quartz sand and heated to melting temperature.
The melting crucibles therefore consist of riveted or pressed / sintered (seamless) tubes made of molybdenum or tungsten or a combination of Mo/W.
The quartz glass tubes or rods are removed through an orifice. The heating system consists essentially of tungsten mesh or rod heating elements. To achieve or regulate the desired dimensions, a plug and plug pole made of refractory metals are necessary in addition to the orifice plate.
