Technical Specifications
Alumina Coated Evaporation Baskets
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.
Providing strongly upward evaporation in the deposition profile, these Tungsten / Alumina Crucibles maintain molten metals evaporants as an induction propelled spinning ball inside the cavity. Most materials can be completely evaporated without loss to the chamber. Recommended evaporant materials are nickel, iron, or their alloys, as well as a broad range of other metals, such as gold, tin, indium and silver. Other materials which can be evaporated include antimony, bismuth, cadmium, cobalt, copper, lead, manganese, palladium, zinc, and alloys such as nichrome and permalloy.
Special designs can be arranged for rare applications not covered by the below listed crucible sizes.
The following are maximum recommended usage parameters for achieving a calculated wire temperature of 1525C, and an estimated surface temperature of the Crucible of 1475C.
