Products Description
Tungsten heaters are usually tungsten wires made into strips folded into a hollow hood in the middle. The tungsten heater produces high temperatures when this hood is energized.The tungsten wire mesh heater for sapphire crystal growth furnace is mainly a heater made of tungsten wire,plays a decisive role in forming AL2O3 solution turbulence and radial temperature gradient;
Tungsten heating element has great significance to sapphire crystal quality control, energy saving and product service life.
Since tungsten and molybdenum materials have low saturation vapor pressure, low coefficient of thermal expansion and good high temperature strength, they are a better choice for heating elements in high temperature furnaces.
Features:
1.The purity of tungsten heating element is more than or equals to 99.95%;
2.The density of this kind of heating element is above 19.1g/cmm³;
3.The application temperature environment should be no more than 2400℃.
4.Our company can produce tungsten heating element according to the customer drawing.
