Tungsten Heater For High Temperature Vacuum Environment
1. Description of Tungsten Heater For High Temperature Vacuum Environment:
Tungsten Heater melting point of tungsten is as high as 3420ºC, it has excellent high temperature strength, and it also has very good corrosion resistance to molten alkali metals and vapors. Its extremely high thermal stability ensures that it can still work normally in a high temperature environment.
Tungsten heater has the characteristics of high strength and hardness, good high temperature performance, low resistivity, small expansion coefficient, and small electronic work function. It is a widely used high temperature resistant metal material.

5. Application of Tungsten Heater For High Temperature Vacuum Environment:
When used as a heat source in the sapphire growth furnace, tungsten heater components have a significant impact on the Al2O3 melt's ability to create turbulence and radial temperature gradient. Therefore, the quality control of sapphire crystal, energy efficiency, and service life are greatly influenced by high-purity and high-density tungsten heater components with careful manufacture and acceptable design.
With the wide application of the LED industry, the demand for sapphire, the substrate material of LEDs, has grown exponentially in recent years. Since the crystallization temperature of sapphire reaches above 2200°C, the crystallization process requires high temperature stability and thermal field environment. Therefore, a tungsten heating heater with high melting point and stable performance at high temperature with less pollution is used in the sapphire crystal growth furnace. has been widely used.
The birdcage type tungsten heating element made of tungsten material can well meet the environmental requirements of the sapphire crystal growth furnace for temperature stability and thermal field.
