Product Description

Pyrolytic Boron Nitride of PBN LEC Crucible
Characteristic
1.Product color is between ivory white and orange-brown,nontoxic,imporosity,east processing.
2.The purity is up to 99.99%, surface densification,good has barrier properties.
3.The strength increases as temperature rises and peaked at 2200ºC, heater-resistance.
4.Acid,alkali,salt and organic reagent resistant.Meanwhile,it does not react with the
 majority of molten-metal and semiconductor material.
5.Excellent thermal shock resistance,excellent thermal conductivity,low thermal expansion coefficient.
6.High resistance,high dielectric strength,low dielectric constance,low dissipation factor,
  excellent microwave and infrared ray ability.
7.It has obvious anisotropy in the mechanics, heat and electricity.
