We have had great success with Sage.
<a class="moz-txt-link-freetext" href="https://www.sage4sales.com/products/crucible-liners">https://www.sage4sales.com/products/crucible-liners</a> They are very
helpful/knowledgeable and they also supply crucible shims so you can
get more heat out of your system at lower e-gun powers. A plus for
some materials.<br>

Those are general purpose crucibles. Once e-beam
evaporation is mentioned, it is a pretty specific –
and different - product type. While “crucible” is a
common term used for those, “hearth liners” is a
more precise one if confusion has to be avoided.
Frankly speaking, even original question from
Alexey used the term “liner”; my fault in switching
to lab slang. </p>

<p class="MsoNormal">From the general
perspective...<br>
<br>
La is an active metal, it slowly
oxidizes in the air. It is very
feasible that it may react with
carbon and form carbide, if melted
in carbon crucible. So the way I
read that crucible selection is "do
not use carbon! Use something else".
Yellow layer of Aluminum Carboide
can become a problem with carbon
crucible as well, so at least this
is a feasible assumption.
<br>
As an active metal, again, it will
wet most other crucibles - I don't
think that can be avoided. Density
of Liquid La is somewhat below
solid, but not too much - so I
suspect it may be breaking crucibles
like Al, so beware of ceramic ones.
Otherwise, I would be looking at
crucible price - those materials
must be steep. <br>
<br>
If you have to justify the use of
metal in evaporator, compare La with
Al. It seem to be on the same page
from e-beam deposition perspective.

Hello Alexey,<br>
<br>
I have several questions if you
don't mind me asking:<br>
<br>
What gas environment do you intend
to use for evaporation? <br>
What is the end product you are
looking to produce with the use of
this material?
<br>
Are you looking for liners that
allow for best adhesion of over
spray? Or, looking at concerns with
contamination from secondary
deposition?<br>
<br>
I can't say that I have a background
on this material, but I would be
interested in knowing the use for
this material if it can be
disclosed.<br>

Subject: [labnetwork] Lantanum
evaporation<br>
<br>
Hello All,<br>
We are thinking about e-beam
evaporation of Lanthanum.Kurt Lesker
recommends either tungsten or
tantalum liner and I am wondering
what could be the difference in this
case. I also found out that
Thermionics thinks that alumina
liner will work as well.<br>
Could anybody please give a
comment, either on evaporation of
the lantanum, or on the liner
material?<br>
Thank you very much<br>
