Electron Beam Evaporation Coating Conductive Boron Nitride Crucible BN Crucible

Application

Conductive boron nitride crucibles are high-purity, smooth crucibles designed for electron beam evaporation coatings. It has excellent high temperature resistance and thermal cycle performance, and does not react with various metals and ceramic rare earths. The crucible remains intact even under rapid heating and cooling conditions. It has applications in alloy melting, rare earth and ceramic sintering, and electron beam evaporation coating. It is often used in thermal evaporation processes such as high-frequency induction heating, coating, electron beam evaporation coating, aluminum plating, and silicon plating.

The conductive boron nitride crucible has high purity, high finish, and excellent electron beam evaporation coating performance. They can increase evaporation rates, accelerate material switching, improve thermal stability and reduce power requirements, ultimately increasing productivity and cost efficiency.

Advantage

• The film has good finish, high purity, less pollution and long service life.
• Excellent high temperature resistance, heat cycle resistance.
• Low thermal expansion, resists wetting by most molten metals.
• Heat resistance up to 2000℃, boron nitride does not react with aluminum and is not easy to volatilize.
• Increased evaporation rate; Increased evaporation rate reduces cycle time and increases overall yield.
• Fast material changeover; Conductive boron nitride crucibles facilitate fast material changeover, minimizing chamber downtime and increasing process efficiency.
• Enhanced Thermal Stability; These crucibles have increased thermal stability, reducing heat transfer from the crucible itself and ensuring consistent and controlled evaporation.
