Your online sources are correct, you cannot use refractory metal liners for Pt. We tried it (tungsten liner) and the Pt alloyed with the liner after a few depositions, causing the liner to totally collapse. Would not advise. </div>

Hello,</div>

Does anyone have experience using refractory metal crucible liners for e-beam evaporation of platinum?</div>
<div class="x_elementToProof" style="font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
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>
