PBN Products

1.  Product Instruction
      Pyrolytic Boron Nitride (PBN) is a kind of advanced ceramic, can be produced with 99.999% purity in high density. It made by ammonia and       Boron halide through Chemical Vapor deposition(CVD) process in high temperature and high vacuum condition:NH3 +BX3=BN+3HX , it can         be produced as PBN plates, and also can be produced as PBN final products directly like crucible, boat, coating, etc.
               

2.  Main Features

      It’s different from BN, there is no traditional process of hot pressing, no need any kinds of agglutinant, so the products have very obliviously       features as follow:
  1.        ●  Non-toxic and tasteless
  2.        ●  High purity(＞99.999%)
  3.        ●  No reaction with acid, alkali, salt and other organic reagent at room temperature
  4.        ●  A little corrode in melt salt and alkali, but it can resistance any kind of acid in high temperature.
  5.        ●  No reaction with melt metal, semiconductor and other compound.
  6.        ●  Excellent oxidation resistant below 1000℃
  7.        ●  Excellent thermal shock resistance
  8.        ●  Can be used in high-temperature, no sublimation point, will be decompose into B&N
  9.        ●  High electrical resistance, good electrical insulating property
  10.        ●  Smooth surface, pore-free, not melt with most of semiconductor

  • 3.  Product Application
  1.        ●  Crystal growth (VGF, LEC Crucible)
  2.        ●  Molecular Beam Epitaxy(MBE) Crucible
  3.        ●  Polycrystalline Synthesis Boat
  4.        ●  OLED and MBE Effusion Cell
  5.        ●  MOCVD Heater
  6.        ●  PBN Infrared Window
  7.        ●  Traveling Wave Tube (TWT) (PBN Support Rod)
  8.        ●  PBN Coating Graphite
  9.        ●  High temperature, vacuum equipment insulato

MOCVD Heater

Introduction MOCVD（Metal-organic Chemical Vapor Deposition）is a special process to grow semiconductor thin films on the matrix. It was developed on the basis of vapor phase epitaxial (VPE) growth, and has become a new technology in VPE. The source materials of crystals grown by MOCVD are metal organic compound and hydride. The metal generally from group Ⅱ or Ⅲ when the later is made by the elements of group V、Ⅵ. The vapor phase epitaxial growth on substrates follows the method of thermal decomposition reaction, and gains semiconductive chemical compounds of the group Ⅲ-V,Ⅱ-Ⅵ, and their thin layer crystal materials of multiple solid solution. The resistance wire heater mainly used in the equipment of Thomas (Have been acquired by aixtron). The heating wire is generally made of tungsten, and the reflective liner is made of PBN. Resistance heating takes radiation heat transfer as the mainly principal. To achieve a completely uniform temperature distribution, it optimizes structure of

Introduction The PBN/PG ceramic heater combines three layers of ultra-high purity ceramics, PBN-PG-PBN to produce an advanced micro-ceramic heating element system. Both our PBN heater (Pyrolytic Boron Nitride) and PG heater (Pyrolytic Graphite) are manufactured by high temperature CVD. These high performance elements exhibit outstanding thermal properties in a ceramic heater, including high thermal conductivity and anisotropy.
