Electron beam crucible liners
Electron beam deposition sources are equipped with a thermal element filament for electron emission, electromagnets for shaping and positioning the electron flow, and an appropriately designed water-cooled copper furnace to accommodate the source material to be deposited. Many materials react destructively with these copper furnaces at the temperatures typically encountered during vacuum deposition. To prevent thermal interaction with the copper hearth and to ensure an even distribution of heat within the source material, it is often beneficial to use a hearth liner during electron beam deposition.
These pads can be made in a variety of shapes and sizes to accommodate all commercially available electron beam sources. The composition of the liner is carefully matched to the material being deposited to minimize heat-generating chemical interactions and maximize thermal stability of the evaporation process.
We can supply crucible liners for electron beam evaporation. Available in different materials and sizes to suit electron guns from different manufacturers. Please contact us for details and quotation.
We also produce thermal crucibles and HTE/LTE crucibles in a variety of materials.
