PBN0922 PBN Crucible, Pyrolytic Boron Nitride Crucible

Pyrolytic Boron Nitride Crucible Description

Compared with normal boron nitride ceramic, pyrolytic boron nitride (PBN) has a much better purity level. PBN crucibles and other pyrolytic boron nitride products are synthesized on the mold by chemical vapor deposition (CVD) process, with BCl3 and NH3 at high temperature and low pressure. The PBN products are extremely pure, as the purity of vapor is easier to be controlled. Most PBN products made from the CVD process have a total impurity of less than 100 ppm, which means the purity is better than 99.99%. With such a high purity level, PBN crucibles are ideal products for semiconductor industries.

PBN Crucible, Pyrolytic Boron Nitride

Similar to graphite, boron nitride has great strength at high temperatures. High purity PBN products have even better mechanical properties. As the solid material is formed by the CVD process, the density of the products could almost reach the theoretical value. PBN products provided by Advanced Ceramic Materials also have great thermal shock resistance. Plates of PBN could be heated to more than 2000 degrees and dropped into the water without getting broken.

PBN Crucible (Pyrolytic Boron Nitride Crucible)
Average rating:

by Tony Williamson on PBN Crucible (Pyrolytic Boron Nitride Crucible)

Worked great for me. I melted down a bunch of scrap copper wire from old TVs in it with a mapp gas torch. It held up great, No cracking for an hour of being heated and didn't leave any ash residue/impurities on the copper. i would describe the size as economical, which is what I was looking for.

by Adam Gimp on PBN Crucible (Pyrolytic Boron Nitride Crucible)
Very good quality. Heats up evenly. Great for aluminum.

This crucible is just the right size for a homemade foundry. We've been able to do dozens of aluminum melts using charcoal with no undue wear on the crucible. It looks like it will hold up for a good while.
