Intermetallic (BN-TiB2) E-Beam Crucibles Evaporator Boat for E-Beam Sources
Innovacera can provide a range of crucibles for electron guns, which can also be designed and customized to meet specific needs. May I know if you have chosen the most suitable crucible for aluminum plating? This article explains in detail how to choose it. Let’s go down. Aluminum will form alloys with tungsten crucibles, molybdenum crucibles, and tantalum crucibles, which cause corrosion on the inside of the crucible and also contaminate aluminum. At the same time, the film layer has been contaminated, such as the film being black, dark, and even spotted. Aluminum will also form yellow aluminum carbide with carbon in graphite crucibles, and the formed aluminum carbide will evaporate onto the sample, causing the film to turn yellow. The use of boron nitride crucibles, alumina crucibles, or quartz crucibles is prone to electron beam defocusing issues. The main reason is that the crucible is not conductive, and the excess electrons in the crucible accumulate, resultin...
