Molybdenum Shield

Molybdenum Heat Shield is an assembly with the multi-layer molybdenum plates and the riveted joints. Due to the reflective properties of the molybdenum sheet, the thermal radiation can reflect to the work piece at the center of the thermal field.

Application: Molybdenum Heat Shield is used in the sapphire growth furnace or the high temperature vacuum furnace. For more details, please refer to the book chapter below:

The molybdenum heat shield can be divided into molybdenum up shields, molybdenum side shields and molybdenum bottom shields.

Standard vacuum furnace in a 1300°C operating temperature, the heat shields are two layers of molybdenum sheets with three-layer stainless steel sheet outside. If a higher operating temperature is required, both the number of layers and the thickness of each layer should be increased. If temperatures in excess of 1650°C, the tantalum sheet can be used to replace the molybdenum sheet.

We can offer the molybdenum heat shield with diameter 75’’ max. and height 75’’ max. Custom Work on your drawing is available, and we can offer the molybdenum parts and assemblies on request. Please contact us for more details.
