====== Choosing a Crucible ======

Important information on deposition of different materials (as well as which crucibles to use) is found on the [[https://www.lesker.com/newweb/menu_depositionmaterials.cfm?section=evapac&init=skip|Kurt J. Lesker site]].

A common reason for crucibles to break: the user shuts the power supply off or has a very short ramp down time for power after the deposition is done. This causes the rapid solidification of the melt, and this stresses out the crucible liner.

===Crucible Types for Common Materials===

FABMATE crucibles can be used for any of the common materials. Sometimes there is a cheaper option available. Graphite and FABMATE crucibles are the same price.

[[https://www.lesker.com/newweb/deposition_materials/depositionmaterials_evaporationmaterials_1.cfm?pgid=al1|Aluminum]] - FABMATE (P/N EVCFABEB-1)

[[https://www.lesker.com/newweb/deposition_materials/depositionmaterials_evaporationmaterials_1.cfm?pgid=cr1|Chromium]] - FABMATE, graphite (P/N EVCEB-1), tungsten. 

[[https://www.lesker.com/newweb/deposition_materials/depositionmaterials_evaporationmaterials_1.cfm?pgid=fe1|Iron]] - FABMATE (Suggests using for one run only. Check for cracks before every run!)
