Intermetallic Crucible (BN-TiB2)
Intermetallic Crucible
Intermetallic crucibles have proven to be a reliable choice for thermal evaporation of aluminum. Due to the wetting characteristics of liquid aluminum, taller crucibles help inhibit the material's spillover by maintaining a cool lip around the top. Tall intermetallic crucibles offer a longer lifetime of both the crucible itself as well as the crucible heater.
Thin films of titanium can also be evaporated from intermetallic crucibles. The film thickness may be limited to 500Å. The crucible may need to be replaced for each subsequent run.
