Protective screens are tungsten sheets, riveted or solid. The blanks are inserted into each other, the space between the cylinders is filled with spacers of a special shape made of tungsten or molybdenum, or a combination thereof. The resulting design is subjected to high temperature processing. Such heat-resistant screens are characterized by high thermal stability, energy efficiency and maximum stability during operation.

Uses of tungsten screens:

Heat-resistant screens are used in vacuum and hydrogen furnaces, electrovacuum devices, to stabilize the temperature inside a single-crystal growing plant, when melting glass, etc.
