GWDL W-Mo Heating Shield

The GWDL - tungsten-molybdenum heating screen can be understood as a composite heating element made of tungsten and molybdenum materials, featuring a grid-like (or screen-like) structure, commonly used in extremely high-temperature environments.

Main Features and Advantages:

1. Extremely High Operating Temperature:
   The maximum operating temperature can exceed 2000°C (depending on the ratio of tungsten to molybdenum and the structural design), making it particularly suitable for ultra-high-temperature processes.
2. Excellent Vacuum Performance:
   Tungsten and molybdenum have very low vapor pressures at high temperatures, which minimizes evaporation, prevents contamination of furnace products, and helps maintain vacuum integrity.
3. Good Thermal Stability:
   It resists deformation at high temperatures, maintaining structural stability and ensuring uniformity of the thermal field.
4. Strong Corrosion Resistance:
   In vacuum or inert atmospheres (such as argon or hydrogen), it is resistant to corrosion from various chemical environments.
5. High Thermal Efficiency:
   The screen-like structure design contributes to the formation of a uniform and focused heating zone.

Main Application Fields
         This heating screen is a core component of high-end thermal equipment, primarily used in:

      1.Vacuum Sintering Furnaces: For sintering tungsten carbide, ceramic materials (such as zirconia and alumina), refractory metals (such as tungsten, molybdenum, and tantalum), and their alloys.

      2.High-Temperature Annealing Furnaces: Used for high-temperature annealing processes of materials such as monocrystalline silicon and gallium arsenide in the semiconductor industry.

      3. Chemical Vapor Deposition (CVD) Furnaces: For producing materials like silicon carbide crystals and diamond thin films.

      4.Scientific Research and Experimental Furnaces: Experimental equipment used by universities and research institutions for ultra-high-temperature material studies.
