Ceramic Conductive Evaporation Boat are devices used for evaporative deposition of thin films. They are primarily made of ceramic material with a layer of aluminum film on the surface. These evaporation boats feature high electrical conductivity and thermal stability, allowing them to operate stably in high-temperature and vacuum environments. Ceramic Conductive Evaporation Boat are widely used in fields such as solar cells, flat panel displays, and thin-film coatings.
◐ Made from high-purity, premium raw materials, ensuring excellent chemical properties.
◐ Manufactured with using internationally advanced vacuum hot-press sintering technology, guaranteeing superior physical properties.
◐ The sintering process employs bidirectional pressing to ensure consistent bulk density of the products.
◐ Production equipment is digitally controlled to ensure stable and consistent product quality.
◐ Unique process formulation optimizes the composition structure, enhancing the evaporation boat's thermal shock resistance and fracture strength, improving aluminum liquid spreading ability and evaporation efficiency, increasing resistance to aluminum liquid corrosion, and extending the working life.
