Whether you need Aluminum Oxide E-Beam Crucibles or ceramic evaporation source crucibles from a China factory, we deliver consistent quality and excellent thermal performance for high-vacuum applications.

⚠ Usage Tips for Electron Beam Evaporation Crucibles

1. Gradual Heating to Prevent Power Fluctuations and Damage
For optimal results, heating power should closely approach the target evaporation power. Before initiating deposition, preheat the material using two-stage power (ramp-up and soak) to bring it near the evaporation point. Sudden power surges can cause sharp thermal stress, increasing the risk of Alumina E-Beam Crucibles cracking.

2. Avoid Residual Coating Stress
Unused coating material cooling on the crucible wall can lead to internal stress. To extend the service life of your vacuum evaporation alumina crucibles, try to evaporate all the coating material before powering down.

3. Use Conductive Crucible Liners When Possible
During electron beam evaporation, using a conductive crucible can help avoid beam deflection caused by charge buildup on insulating surfaces. Especially for high-value coatings like gold, a grounded path ensures beam stability.
