<p>Hi Cliff,</p>
<p><br>
</p>
<p>We had the same issue with Al in graphite crucibles.</p>
<p><br>
</p>
<p>Al deposition in intermetallic crucibles has been working perfectly for us. </p>
<p><br>

<p>Hi All,</p>
<p><br>
</p>
<p>We've been having crucible cracking issues with out Al e-beam evaporation source. In short it cracks its crucible after just a few uses. This wasn't so bad when it happened ever 4-5 months, but not its happening about every week or two. I've tried a variety
of crucibles, had the most luck with carbon crucible. Is there anything else out there we should be trying?</p>
<p><br>
</p>
<p>Cheers,</p>
<p><br>
