MetalsTek Fabmate-type graphite crucible liners are manufactured from selected high-purity graphite for demanding e-beam evaporation applications. They offer good thermal stability, precision-machined dimensions, and broad material compatibility in vacuum or inert atmosphere environments. For applications where quartz or other liner materials are not suitable, graphite liners may provide a practical alternative, subject to process validation.
MetalsTek Fabmate-type graphite crucibles are available in commonly used dimensions for e-beam evaporation systems. They are designed as graphite crucible liners for applications where dimensional compatibility, thermal stability, and clean evaporation performance are important.
Manufactured from selected high-purity graphite, these crucibles offer good thermal conductivity, high-temperature stability, and reliable performance in vacuum and inert atmosphere environments. The material is suitable for many standard evaporation processes.
Each crucible is machined according to specified dimensions, including top outer diameter, height, wall thickness, bottom profile, and wall angle. Custom dimensions can also be produced based on drawings or sample requirements.
Surface treatment or anti-oxidation coating may be available upon request for selected applications. These treatments are intended to improve surface performance or oxidation resistance under suitable operating conditions, but they should not be considered equivalent to proprietary Fabmate or Poco graphite treatments unless specifically tested and confirmed.
Fabmate-type graphite crucibles can be used with many evaporation materials commonly handled by standard graphite crucibles, including selected metals, alloys, and compounds. Actual compatibility depends on evaporation material, temperature, vacuum level, reaction behavior, and process conditions.
Graphite crucibles provide strong thermal stability in vacuum or inert atmospheres. Maximum working temperature depends on graphite grade, coating condition, atmosphere, heating rate, and application environment.
In addition to standard models, MetalsTek can supply custom graphite crucibles based on drawings, reference samples, or required equipment dimensions. For critical applications, sample testing is recommended before batch use.
MetalsTek Fabmate-type graphite crucibles are not original KJL or Poco products. Product codes and dimensions should be confirmed before order. Performance may vary depending on actual process conditions, and specific chemical resistance, particle performance, or lifetime claims should be validated by customer testing.
Proper handling and setup are essential to extend the lifespan of Fabmate-Type crucibles. Below are common issues and solutions:
E-beam evaporation recipes rely on carefully calibrated ramp/soak power levels:
Improper shutdown after deposition can also damage crucibles:
