Molybdenum Parts For Sapphire-growth Furnace

Sapphire is officially known as “sapphire crystal glass.” It is produced by melting and cooling Al₂O₃ in a high temperature furnace. The current main technologies for sapphire crystal growth are listed as below:

● Kyropoulous Method (KY)

● Edge-Defined Film-Fed Growth Method (EFG)

● Heat Exchanger Method (HEM)

● Vertical Horiaontal Gradient Freezing Method (VHGF)

● Temperature Gradient Technique (TGT)

● Czochralski Method (CZ)

● Verneuil Method (VM)

Molybdenum and tungsten features high temperature resistance, low thermal expansion, high temperature deformation resistance and excellent corrosion resistance. They are ideal materials for furnace construction for sapphire crystal growing. HEXON supplies various molybdenum and tungsten products including semi-finished forms and custom-made components for sapphire growth furnace manufacturers and sapphire crystal producers.
