XTL sintyron high quality pbn conical oled vgf lec mbe crucible

Pyrolytic boron nitride belongs to hexagonal crystal, is a special ceramic material, the purity can reach 99.999%, acid and alkali resistance, oxidation resistance, good thermal conductivity, can be processed. The deposition process of pyrolytic boron nitride is like “falling snow “, and the hexagonal small snow flakes of boron nitride fall on the graphite matrix material one piece in parallel, reaching a certain thickness, and finally made of cooling and stripping.

Main properties of PBN ceramic

1. High purity (>99.99%)

2. High density (>2.12g/cm3)

3. No gas is released at high temperature

4. Uniform thickness, good heating consistency

5. Excellent thermal conductivity and thermal shock resistance

6. High interlayer strength, easy to clean and repeated use

7. Chemically inert, does not react with acids, alkalis, salts and organic solvents at high temperatures

Typical applications of PBN ceramic

1.Crucibles for in-situ synthesis of GaAs, InP, GaP and other semiconductor single crystals.

2. Crucibles and boats for the synthesis of single crystals or polycrystals of other III-V compounds.

3. MBE crucible for molecular beam epitaxy.
