<p>Hi,</p>
<p>Perhaps this was mentioned earlier, but why not use a Cu liner?
I've seen Pt evaporated directly from the hearth.</p>

Does anyone have experience using refractory metal crucible
liners for e-beam evaporation of platinum?</div>

I am currently using Fabmate, which performs well until the
platinum reaches higher temperatures, at which point carbon
contamination becomes an issue. I have had good results using a
tungsten liner for gold, and I’m considering trying tungsten for
platinum as well.</div>

However, I’ve come across online sources suggesting that
refractory metals may not be compatible with platinum. I’d
appreciate any insights or recommendations based on your
experience. Thank you in advance.</div>
