The alumina coated tungsten evaporation basket is an efficient design which acts as an internally heated crucible.
The ceramic 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 only have 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 evaporation 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.
