Alumina Coated Evaporation Sources

Ideal for low power thermal evaporation supplies
low power evaporation baskets alumina coated tungsten wire baskets
The Alumina coated tungsten evaporation basket is an effcient design which acts as an internally heated crucible. The Alumina coated evaporation baskets for vacuum evaporation have the distinct advantage that they require relatively low power (63 to 768 W) to reach a temperature of 1475°C (high enough to evaporate Ni in high vacuum). This will enable many researchers to experiment with thermal evaporation who have only access to low cost, low power evaporation supplies. The closed side crucible form allows to use pallets, grains, wires or even powders as evaporation material for upwards evaporation applications. Molten metal evaporants are contained as an induction propelled spinning ball inside the cavity. Most materials can be completely evaporated without loss to the crucible. A broad range of materials can be used in these alumina coated sources: Au, Ag, Pd, In, Sn, Sb, Bi, Cd, Cu, Pb, Zn, Co, Ni, Fe, Mn and alloys such as Nichrome and Permalloy. Maximum temperature for this type of alumina coated tungsten basket should not exceed 1800°C. There are 6 different type of basket available with a top opening ranging from 0.15" to 0.90".

Tungsten Metal Boats for Evaporation


Two of the tungsten boats listed on this page are a combination of the refractory metal tungsten and an alumina barrier (Al2O3) tungsten and an alumina barrier (Al2O3/>) coating over the tab area. The exposed metal area comprising the bottom of the boat allows the sample to be in good thermal contact with the source. The barrier will tend to help concentrate the heat towards the center. The alumina barrier will inhibit an evaporant (if used as a sample instead of an aperture) from creeping toward the heat sink or from wetting the entire boat.

Alumina Coated Evaporation Source


Replaces alumina crucibles for some specific applications. Good heat transfer yet has alumina inertness. Evaporant does not wet the alumina: no resistant change of the boat when evaporant melts. Due to the non-wetting characteristic, the evaporant forms a sphere when melted resulting in a point source.
