Hi:

This message was originally posted to the optoelectronics forum. I am 
reposting it here, because it is not clear if Tony Springthorpe can get
direct access to the sci.materials newsgroup. All replies should go directly
to him at <ajs@bnr.ca>. Also he would appreciate it if someone could tell
him how he could post messages directly to this newsgroup in the future.

Thank you,

Sandip

Subject: Is there a source of AlN out there?

This is a materials question, rather than a specific comment re'
optoelectronic devices. However,it does have relevance to being able to
prepare high quality epitaxial materials suitable for devices.
Specifically, I am trying to find a source of high purity aluminum
nitride so that I can get crucibles made for an MBE deposition system.
Bulk material is OK, but I would prefer a 100 um coating on a
conventional boron nitride crucible.
Anyone out there know where I might find such material, or another more
relevant NET where I might pose the same question?
Thanks for any help you can give.
