Product Description
Boron Nitride Evaporator Boats for Industrial Metallization
Boron Nitride Ceramics are engineered for extreme environments requiring electrical insulation, thermal insulation, high temperature resistance up to 1850°C, and chemical resistance. These advanced materials serve critical applications in automotive, electronics, electrical engineering, aerospace, medical science, and scientific research sectors.
Optimizing Evaporator Boat Performance
Application Process
- Resistance-heated boats operate in vacuum chambers at 1500-1650°C (2732-3002°F) to evaporate metals including aluminum, copper, tin, and silver
- Metallized films and papers are utilized across food packaging, capacitor film, decorative, and electronic industries
Maximizing Operational Life
- Verify alignment and smooth surface of electrical contacts
- Utilize graphite tape for uniform electrical and thermal contact
- Employ aluminum wire pieces for initial temperature calibration
- Position wire feed centrally on boat surface
- Follow 12-14 minute heat-up cycle for proper reannealing
- Begin with 75% normal feed rate and adjust power for optimal wetting
- Gradually increase wire feed rate during first 15 production minutes
- Post-coating sequence: stop wire feed, then cut power after 20-30 seconds
- Allow 2-minute cooling period before vacuum release
- Clean boats with wire brush after each cycle
