Product Description
Tungsten/molybdenum parts in the sapphire furnace

Tungsten/molybdenum crucible
Since the melting point of tungsten has reached 3410C, and molybdenum is 2610C. For sapphire crystal growth furnace, high-purity, high- density, no internal -crack tungsten/molybdenum crucible with other features of exact measurement and smooth surface has decisive influence on success ratio of seed growth, quality control of pulling crystal, metamictization pot-committed and service life during sapphire growth process.

Tungsten heater
Tungsten heater components, as heat source in the sapphire growth furnace, have decisive effect for Al2O3 melt to form turbulence and produce radial temperature gradient. Therefore, high-purity and high-density tungsten heater components with delicate manufacture and reasonable design have great significance towards quality control of sapphire crystal, energy saving and service life

Molybdenum sheet
After rolling and processing with deflection reaching 60%, the density of molybdenum sheet basically
Comes close to molybdenum's theory density. Therefore, molybdenum sheet possesses the properties of
High density, balanced internal structure and excellent high creep strength temperature. Molybdenum sheet
Is widely used in reflection shield, cover plate applied in the sapphire growth furnace, reflection
Shield, heating tape, connecting pieces applied in vacuum furnace

Molybdenum reflection shield
As the heat-shield parts in the sapphire growth furnace, the most decisive function of molybdenum
Reflection shield is to prevent and reflect the heat in the furnace. Heat-shield parts with high-density, exact-
Measurement, smooth-surface, convenient-assembly and reasonable-design has great significance in
Improving the crystal-pulling.

Upper and bottom cover plate
As the heat-shield parts in the sapphire growth furnace, the most decisive function of upper
And bottom cover plate is to prevent and reflect the heat in the furnace. Heat-shield parts
With high-density, exact-measurement, smooth-surface, convenient-assembly and
Reasonable-design has great significance in improving the crystal-pulling

In addtion we can provice the full sets of molybdenum/tungsten parts for capability 30kgs, 60kgs, 100kgs, 120kgs.
