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:

Boron Nitride Ceramics Boron nitride ceramics are made by hot pressing boron nitride powders at high temperature and pressure�¯�¼? they can easily be machined into rods, bars, plates and even intricate custom shapes. The excellent highly exceptional thermal, physical and chemical characteristics of boron nitride ceramics make it ideal for solving tough challenges in a wide range of industrial applications.�?� Excellent thermostable performance (Temperature �¢?�¥ 2000�¢?? in vacuum and inert atmosphere) Excellent thermal shock resistance Excellent lubricating properties High thermal conductivity High electrical resistivity Good chemical inertness Non-wetting (without oxidation) Excellent machinability It is widely used in many fields The ceramics are hard and can be made into high-speed cutting tools and drill bits used in geological exploration and oil drilling. Different shapes, can be used for high temperature, high voltage, insulation and heat dissipation components. Ceramics can be used to make packaging materials to prevent neutron radiation. Ceramics can be used to make special electrolysis and resistance materials under high temperature conditions. We can make different shapes of ceramics according to your requirements and your drawing, welcome and looking forward for your inquiring!
