Resistance Heated Ceramic Evaporation Boat 1.5-3.0 OD for Metalizing at 1850°C Working Temperature
Boron Nitride Ceramics are engineered for extreme environments requiring electrical insulation, thermal insulation, high temperature resistance, and chemical resistance. These materials are widely applied in automotive, electronics, electrical engineering, aerospace, medical science, and scientific research applications.
Resistance-heated boats and crucibles operate in vacuum chambers at temperatures ranging from 1500-1650°C (2732-3002°F) to evaporate various metals including aluminum (Al), copper (Cu), tin (Sn), and silver (Ag). The resulting metallized films and papers serve critical functions in food packaging, capacitor film production, decorative applications, and electronic industries.
