Aluminum is one of the most common metals in the world. It can be found in kitchen utensils, cars, street lights, and the popular aluminum foil food packaging. Aluminum is a silvery-white, metallic material. It is light, malleable, ductile, and non-magnetic under normal conditions.
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).
Evaporation is a common method of thin-film deposition. The source material is evaporated in a vacuum. The vacuum allows vapor particles to travel directly to the target object (substrate), where they condense back to a solid state. Evaporation is .
(Regular and uniform vacuum in the metallizer, proper way of clamping the boats, 'break-in' procedure of the evaporation boat, right way of heating-up and then cooling down of the boats, are some of the external parameters affecting the overall boat performance.). I have, earlier, written a detailed article on the above topics.
The alumina ceramic coated tungsten evaporation basket is an internally heated crucible that is designed to provide the means for vacuum evaporation of a number of various metals, and at the same time provide a more useful crucible life with these type metals.
