Pyrolytic Boron Nitride Crucible
1.Merchandise coloration is among ivory white and orange-brown,nontoxic,imporosity,east processing.
2.The purity is up to ninety nine.ninety nine%, surface densification,excellent has barrier properties.
three.The power boosts as temperature rises and peaked at 2200ºC, heater-resistance.
four.Acid,alkali,salt and natural and organic reagent resistant.Meanwhile,it does not react with the
majority of molten-steel and semiconductor material.
5.Exceptional thermal shock resistance,outstanding thermal conductivity,minimal thermal expansion coefficient.
six.Large resistance,large dielectric power,minimal dielectric constance,lower dissipation issue,
excellent microwave and infrared ray potential.
seven.It has apparent anisotropy in the mechanics, warmth and electric power.
Application
one.The crucible and substrate of semi-conductor single crystal and III-V compound synthesis
2.LEC crucible for the synthesis of GaAs,InP,GaP
3.MBE crucible for Molecular Beam Epitaxial.
4.VGF crucible
5.Other customizable PBN products
