Boron Nitride Composite Ceramic Evaporation Boat
Ceramic evaporation boat is the very good material for vacuum aluminizing.
Description
Ceramic evaporation boat is a 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 Nitride and Titanium Diboride) and can meet the strict requirement for metal film and paper with good thermal shock resistance and good chemical inertness. Boron Nitride evaporation boat has the advantages of long service life, uniform evaporation, fast heating speed and high evaporation efficiency.
Boron nitride ceramic evaporation boat is widely used in vacuum aluminium plating packing factories, 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.
● Good resistance to molten aluminium or any other molten metal corrosion increases the boat’s life.
