Tungsten heat shield

Tungsten sheet is very good material for high temperature Hot-Zone construction. It is work well at 1500 - 2200 DC.

The heat shielding is make up of multiple layers of tungsten sheet with spaces between each layer. Generally, a heat shielding often consists of 3 6 layers of tungsten sheet backed by molybdenum sheet. For higher operation temperatures, the number of tungsten layers is increased as well as the thickness of each layer.

Application : Hot-Zone for vertical cylindrical vacuum furnace.

We also supply heat shield make of  Molybdenum, TZM, MoLa
