An evaporation source frequently used by evaporative coating machines is a device for heating films to vaporize and evaporate. At present, the used evaporation source is mainly divided into resistance heating, electronic beam heating, induction heading, electric arc heating, laser heating and many other modes.

Resistance heating type evaporation source: resistance-type evaporation sources are simple, economic and reliable, and have been applied universally. Heating materials of resistance heating type evaporation sources are generally selected from W, Mo, Ta, Nb and other high-melting-point metals as well as Ni and Ni-Cr alloy.

The evaporation source has the following features:

1. High melting point; 2. low saturated vapor pressure; 3. stable chemical performance.

Parts using tungsten-molybdenum products in resistance heating type evaporation sources include:

Heater 2017-11-21 00:00:00
With extremely low saturated vapor pressure, low thermal expansion coefficient and extremely good high-temperature strength, tungsten and molybdenum materials are the best choice for high-temperature in-furnace heating elements.

Shielding 2017-11-21 00:00:00
Tungsten-molybdenum materials are suitable to be used for shielding at the temperature of 1,300℃ to 2,800℃, which reserve the heat in an effective interval in the modes of heat reflection and convection obstruction.

Hot Isostatic Pressing Cylinder 2017-11-21 00:00:00
Heat screens applied in hot isostatic presses are called hot isostatic pressing cylinders. Hot isostatic pressing cylinders have higher requirements than common heat screens when working under the conditions of 2000℃ and 2000MPa. To ensure the air tightness, Achemetal has adopted a thermal spraying process based on welding.

Crucible 2017-11-21 00:00:00
Tungsten powder or molybdenum powder is directly subjected to sintering molding or hot isostatic pressing molding, and is mostly used for manufacturing large crucibles of sintering furnaces, crystal growth furnaces, glass smelting and rear earth smelting equipment. Particularly, these kinds of crucibles are used in furnaces of growing sapphire crystals by KY method, EFG method and heat exchange method in large quantity. Usually, the wall thickness is 8-15mm; the diameter is 100-600mm; the height is 50-700mm. The purity of these kinds of crucibles: W≥99.95%; the density usually can reach 18.2g/cm3; and the density can reach more than 18.8g/cm3 by a hot isostatic pressing technology as required specially. The density of molybdenum crucibles usually can reach about 10.0g/cm³.

Loaded Boat 2017-11-21 00:00:00
In sintering furnaces or thermal treatment furnaces, tungsten or molybdenum materials are required to be prepared into containers when the processed materials are powder or granules. Loaded boats can be designed in different shapes according to different shapes and ventilation conditions of the processed materials. Achemetal can provide boat vessels made of pure tungsten, pure molybdenum as well as tungsten alloy and molybdenum alloy according different requirements on the operating temperature and strength as well as purity. Tungsten-molybdenum loaded boats manufactured by Achemetal feature good high-temperature deformation resistance and high dimensional accuracy.

Rack 2017-11-21 00:00:00
Racks are used for placing and transferring workpieces needing to be processed in high-temperature annealing furnaces and sintering furnaces, and have extremely high requirements on the high-temperature strength of materials for manufacturing racks. Achemetal can manufacture pure tungsten, pure molybdenum, molybdenum-lanthanum alloy and titanium-zirconium-molybdenum alloy racks, to enhance creep resistance and high-temperature strength of materials.
