Ceramic evaporation boat is an evaporation container widely used in vacuum evaporation technology to melt various metal materials, such as aluminum, zinc, etc. It is suitable for vacuum evaporation packaging materials, capacitor metallization coating, display coating, solar cell coating, hot stamping coating, anti-counterfeiting logo coating, reflective coating, paper making, textile aluminum plating and other industries. Can be professionally designed and customized according to customer requirements.
Evaporation boat is made of high-purity&quality boron nitride powder with specific auxiliary materials, and is made of bidirectional pressing using internationally advanced vacuum hot-pressing sintering technology. The unique process formula optimizes the component structure to ensure excellent physical properties such as electrical conductivity and thermal conductivity, as well as chemical properties such as corrosion resistance and high thermal stability, enhance the thermal shock resistance and fracture strength of the evaporation boat, and improve the spreading ability and evaporation efficiency of the metal solution. Increase corrosion resistance and extend service life.
