Ceramic Evaporation Boat For Metallizing Film

In the industrial aluminum evaporation industry, graphite is widely used as an evaporating boat in the early stage. Because graphite is easy to be corroded by liquid aluminum and is very easy to be oxidized, the service life of graphite evaporating boat is short. Titanium diboride has good conductivity, corrosion resistance, oxidation resistance, boron nitride has good heat insulation, corrosion resistance, easy workability, and titanium diboride and boron nitride in the high temperature will be on the liquid aluminum has good wettability, has formed by the titanium diboride of boron nitride composite ceramic evaporation boat instead of graphite evaporation boat trend, It has been widely used in industrial evaporation aluminum industry.
