Product Description
Boron Nitride Ceramics are engineered for extreme environments requiring electrical insulation, thermal insulation, high temperature resistance up to 1850°C, and chemical resistance. These materials serve critical applications across automotive, electronics, electrical engineering, aerospace, medical science, and scientific research sectors.
Evaporator Boat Applications
Resistance-heated boats operate in vacuum chambers at 1500-1650°C (2732-3002°F) to evaporate metals including aluminum (Al), copper (Cu), tin (Sn), and silver (Ag). The resulting metallized films and papers are essential components in food packaging, capacitor films, decorative applications, and electronic industries.
Performance Optimization Guidelines
To maximize evaporator boat lifespan and ensure optimal performance:
- Verify alignment and surface smoothness of electrical contacts
- Utilize graphite tape for uniform electrical and thermal contact
- Employ aluminum wire pieces during initial heat-up to determine correct operating temperature
