Conductive Ceramic Evaporation Boat Ceramic evaporation boat is the very good material for vacuum aluminizing strict requirements which has special electrical and thermal properties. It is made of electrically conductive advanced ceramic composites ( Boron Nitrideï¼?Titanium Diboride and Aluminium nitride), and can meet the strict requirement for metal film and paper with good thermal shock resistance and good chemical inertness of liquid aluminum. BN evaporator boat� has the advantages of long service life, uniform evaporation, fast heating speed and high evaporation efficiency. Boron nitride ceramic evaporation boats is widely used in vacuum aluminium plating packing factory, capacitors metallized coating, screen coating, bronzing coating, anti fake mark coating, reflective coating and paper. Features: Good chemical stability Excellent thermal shock resistance ability and bending resistance The molten aluminium spreads easily and evenly. A good resistance to molten aluminium or any other molten metal corrosion increases the boatâ??s life. Technology standard: Working currentï¼?400-900A Working voltageï¼?5-15V Operating temperatureï¼?1300-1750â?? Evaporation rate� ï¼?0.3-0.5ï¼?g/min/ cm�²ï¼? Service lifeï¼?15-20/h Densityï¼?2.8-3.2g/cm�³ Resistivityï¼?200-300�¼�©/ cm Coefficient of thermal expansionï¼?(4-6)*10-6K Bending strengthï¼?>150Mpa.
