Tungsten Heater For Vacuum Metallizing
Heater designs have varied considerably since 1927 when the first indirectly heated cathodes were introduced. At that time, a hairpin tungsten heater was supported by an extruded ceramic insulator and surrounded by a nickel sleeve.
All of these heaters were made in various sizes to meet different heater-power requirements. The ceramic insulating sleeves were usually made of alumina, magnesia, thoria, beryllia, or electrical porcelain. Many factors, such as high cost, contaminants in the ceramics, and slow warm-up time, resulted in the decline of these heaters.
Most of high-temperature vacuum furnaces are electrically resistance heated. Heating elements may be constructed from metal or graphite in a variety of styles. Heating element design takes into account thermal capability, mechanical stability, and configuration and service life. The heating element is the most critical part of the system in terms of material choice.
Tungsten is the best choice for the excellent high-temperature characteristics. Tungsten heating elements is used almost exclusively in vacuum furnaces for higher temperature ranges (1800 to 3000 C for example). The heating element operates at a higher temperature than any other component in the system.
